Basis of Presentation [Abstract]
Basis of Presentation	Note 1. Basis of Presentation Standard Motor Products, Inc. and its subsidiaries (referred to hereinafter in these notes to the consolidated financial statements as “we,” “us,” “our,” “SMP,” or the “Company”) is a leading manufacturer and distributor of premium replacement parts in the automotive aftermarket, and custom-engineered solutions for vehicle control and thermal management categories in diversified end markets. We sell our products primarily to automotive aftermarket retailers, warehouse distributors, original equipment manufacturers and original equipment service part operations in the United States, Canada, Europe, Asia, Mexico and other Latin American countries. The accompanying unaudited financial information should be read in conjunction with the audited consolidated financial statements and the notes thereto included in our Annual Report on Form -K for the year ended December The unaudited consolidated financial statements include our accounts and all domestic and international companies in which we have more than a equity ownership, except in instances where the minority shareholder maintains substantive participating rights, in which case we follow the equity method of accounting. In instances where we have more than a equity ownership and the minority shareholder does not maintain substantive participating rights, our consolidated financial statements include the accounts of the company on a consolidated basis with its net income and equity reported at amounts attributable to both our equity position and that of the noncontrolling interest. Investments in unconsolidated affiliates are accounted for on the equity method, as we do not have a controlling financial interest but have the ability to exercise significant influence. All significant inter-company items have been eliminated. The accompanying unaudited consolidated financial statements have been prepared in accordance with generally accepted accounting principles for interim financial information and with the instructions to Form -Q and Rule - of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by generally accepted accounting principles for complete financial statements. In the opinion of management, all adjustments (consisting of normal recurring adjustments) considered necessary for a fair presentation have been included. The results of operations for the interim periods are not necessarily indicative of the results of operations for the entire year. Reclassification Certain prior period amounts in the accompanying consolidated financial statements and related notes have been reclassified to conform to the 2023 presentation. Reportable Segments Beginning on January 1, 2023, we reorganized our business into three operating segments – Engineered Solutions, Vehicle Control and Temperature Control. The new operating segment structure provides clarity regarding the unique dynamics and margin profiles of the markets served by each segment, better aligns our operating segments with our strategic focus on diversification, and provides greater transparency into our positioning to capture growth opportunities in the future. Prior period segment results have been reclassified to conform to our operating segment reorganization. For additional information related to our segment reorganization, see Note 7, “Goodwill and Acquired Intangible Assets,” Note 16, “Industry Segments,” and Note 17, “Net Sales.”

Summary of Significant Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Note 2. Summary of Significant Accounting Policies The preparation of consolidated annual and quarterly financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amount of assets and liabilities, the disclosure of contingent assets and liabilities at the date of our consolidated financial statements, and the reported amounts of revenue and expenses during the reporting periods. We have made a number of estimates and assumptions in the preparation of these consolidated financial statements. We can give no assurance that actual results will not differ from those estimates. Although we do not believe that there is a reasonable likelihood that there will be a material change in the future estimates, or in the assumptions that we use in calculating the estimates, the uncertain future effects, if any, of disruptions in the supply chain, Russia’s invasion of the Ukraine and resultant sanctions imposed by the U.S. and other governments, the geo-political impact of U.S. relations with China, future increases in interest rates, inflation, macroeconomic uncertainty, and other unforeseen changes in the industry, or business, could materially impact the estimates, and may have a material adverse effect on our business, financial condition and results of operations. Some of the more significant estimates include allowances for expected credit losses, cash discounts, valuation of inventory, valuation of long-lived assets, goodwill and other intangible assets, depreciation and amortization of long-lived assets, product liability exposures, asbestos, environmental and litigation matters, valuation of deferred tax assets, share based compensation and sales returns and other allowances. There have been no material changes to our critical accounting policies and estimates from the information provided in Note 1 of the notes to our consolidated financial statements in our Annual Report on Form 10-K for the year ended December 31, 2022. Recently Issued Accounting Pronouncements Standards not yet adopted as of March There are no recently issued accounting pronouncements not yet been adopted as of March 31, 2023 that could have a material impact on our financial statements.

Business Acquisitions and Investments [Abstract]
Business Acquisitions and Investments	Note 3. Business Acquisitions and Investments 2022 Increase in Equity Investment Investment in Foshan Che Yijia New Energy Technology Co., Ltd. In August 2019, we acquired an approximate 29% minority interest in Foshan Che Yijia New Energy Technology Co., Ltd. (“CYJ”) for approximately $5.1 million. CYJ is a manufacturer of automotive electric air conditioning compressors and is located in China. We determined, at that time, that due to a lack of a voting majority and other qualitative factors, we do not control the operations of CYJ and accordingly, our investment in CYJ would be accounted for under the equity method of accounting. In October 2022, we acquired an additional 3.55% equity interest in CYJ for RMB 1.7 million (approximately $242,000), increasing our minority ownership interest in CYJ from an approximate interest of 29% to 33%. The additional acquired ownership interest in CYJ was paid for in cash funded by borrowings under our Credit Agreement with JPMorgan Chase Bank, N.A., as agent. We will continue to account for our minority interest in CYJ using the equity method of accounting. 2022 Business Acquisitions Acquisition of Capital Stock of Kade Trading GmbH (“Kade”) The following table presents the allocation of the purchase price to the assets acquired and liabilities assumed based on their fair values (in thousands): Purchase price $ 3,176 Assets acquired and liabilities assumed: Receivables $ 790 Inventory 829 Other current assets (1) 1,003 Property, plant and equipment, net 63 Operating lease right-of-use assets 401 Intangible assets 2,395 Goodwill 766 Current liabilities (1,977 ) Noncurrent operating lease liabilities (328 ) Deferred income taxes (766 ) Net assets acquired $ 3,176 (1) The other current assets balance includes of cash acquired.

Restructuring Costs Cost Reduction Initiative During the fourth quarter of 2022, to further our ongoing efforts to improve operating efficiencies and reduce costs, we announced plans for a reduction in our sales force, and initiated plans to relocate certain product lines from our Independence, Kansas manufacturing facility and from our St. Thomas, Canada manufacturing facility to our manufacturing facilities in Reynosa, Mexico. Restructuring expenses related to the Cost Reduction Initiative of approximately $0.9 million were incurred during the three months ended March 31, 2023 consisting of (1) expenses of approximately $0.8 million of employee severance related to our product line relocations, and (2) expenses of approximately $0.1 million related to the relocation of machinery and equipment to our manufacturing facilities in Reynosa, Mexico. Cash payments made of approximately $0.4 million during the three months ended March 31, 2023 consisted primarily of severance payments related to the sales force reduction. Additional restructuring costs related to the initiative, and expected to be incurred, are approximately $1.9 million. We anticipate that the Cost Reduction Initiative will be completed by the end of 2023.

Sale of Receivables [Abstract]
Sale of Receivables	Note 5. Sale of Receivables We are party to several supply chain financing arrangements, in which we may sell certain of our customers’ trade accounts receivable to such customers’ financial institutions. We sell our undivided interests in certain of these receivables at our discretion when we determine that the cost of these arrangements is less than the cost of servicing our receivables with existing debt. Under the terms of the agreements, we retain no rights or interest, have no obligations with respect to the sold receivables, and do not service the receivables after the sale. As such, these transactions are being accounted for as a sale. Pursuant to these agreements, we sold $170.9 million and $155.7 million of receivables during the three months ended March 31, 2023 and 2022, To the extent that these arrangements are terminated, our financial condition, results of operations, cash flows and liquidity could be adversely affected by extended payment terms, or delays or failures in collecting trade accounts receivable. The utility of the supply chain financing arrangements also depends upon a benchmark reference rate for the purpose of determining the discount rate applicable to each arrangement. If the benchmark reference rate increases significantly, we may be negatively impacted as we may not be able to pass these added costs on to our customers, which could have a material and adverse effect upon our financial condition, results of operations and cash flows.

Goodwill and Acquired Intangible Assets [Abstract]
Goodwill and Acquired Intangible Assets	Note 7. Goodwill and Acquired Intangible Assets Goodwill In connection with our operating segment reorganization, we reassessed our reporting units and reallocated goodwill from the reporting units that existed prior to the change to the new reporting units, using a relative fair value allocation approach similar to that used when a portion of a reporting unit is to be disposed of. We performed goodwill impairment tests as of January 1, 2023 on both the reporting units in place prior to the change and the new reporting units, and concluded that the estimated fair values of each of the reporting units exceeded their respective carrying amounts and, therefore, no impairment charge was necessary. Acquired Intangible Assets Acquired identifiable intangible assets consist of the following: March 31, 2023 December 31, 2022 (In thousands) Customer relationships $ 159,447 $ 158,717 Patents, developed technology and intellectual property 14,123 14,123 Trademarks and trade names 8,880 8,880 Non-compete agreements 3,291 3,282 Supply agreements 800 800 Leaseholds 160 160 Total acquired intangible assets 186,701 185,962 Less accumulated amortization (1) (89,683 ) (86,945 ) Net acquired intangible assets $ 97,018 $ 99,017 (1) Applies to all intangible assets, except for trademarks and trade names totaling $2.6 million, which has an indefinite useful life and, as such, is not being amortized. Total amortization expense for acquired intangible assets was $2.2 million and $2.1 million for the three months ended March 31, 2023 and 2022, respectively. Based on the current estimated useful lives assigned to our intangible assets, amortization expense is estimated to be $6.3 million for the remainder of 2023, $8.5 million in 2024, $8.4 million in 2025, $8.4 million in 2026 and $62.8 million in the aggregate for the years 2027 through 2041.

Credit Facilities and Long-Term Debt [Abstract]
Credit Facilities and Long-Term Debt	Note 9. Credit Facilities and Long-Term Debt Total debt outstanding is summarized as follows: March 31, 2023 December 31, 2022 (In thousands) Credit facility – term loan due 2027 $ 96,250 $ 97,500 Credit facility – revolver due 2027 176,750 142,000 Other 101 120 Total debt $ 273,101 $ 239,620 Current maturities of debt $ 57,614 $ 55,031 Long-term debt 215,487 184,589 Total debt $ 273,101 $ 239,620 Term Loan and Revolving Credit Facility In June 2022, the Company entered into a new Credit Agreement with JPMorgan Chase Bank, N.A., as administrative agent, and a syndicate of lenders (the “Credit Agreement”). The Credit Agreement provides for a $500 million credit facility comprised of a $100 million term loan facility (the “term loan”) and a $400 million multi-currency revolving credit facility available in U.S. Dollars, Euros, Sterling, Swiss Francs, Canadian Dollars and other currencies as agreed to by the administrative agent and the lenders (the “revolving facility”). The Credit Agreement replaces and refinances the 2015 Credit Agreement. Borrowings under the Credit Agreement were used to repay all outstanding borrowings under the 2015 Credit Agreement, and pay certain fees and expenses incurred in connection with the Credit Agreement, with future borrowings used for other general corporate purposes of the Company and its subsidiaries. The term loan amortizes in quarterly installments of 1.25% in each of the first four years, and quarterly installments of 2.5% in the fifth year of the Credit Agreement. The revolving facility has a $25 million sub-limit for the issuance of letters of credit and a $25 million sub-limit for the borrowing of swingline loans. The maturity date is June 1, 2027. The Company may request up to two one-year extensions of the maturity date. The Company may, upon the agreement of one or more then existing lenders or of additional financial institutions not currently party to the Credit Agreement, increase the revolving facility commitments or obtain incremental term loans by an aggregate amount not to exceed (x) the greater of (i) $168 million or (ii) 100% of consolidated EBITDA (as defined in the Credit Agreement) for the four fiscal quarters ended most recently before such date, plus (y) the amount of any voluntary prepayment of term loans, plus (z) an unlimited amount so long as, immediately after giving effect thereto, the pro forma First Lien Net Leverage Ratio (as defined in the Credit Agreement) does not exceed 2.5 to 1.0. Term loan and revolver facility borrowings in U.S. Dollars bear interest, at the Company’s election, at a rate per annum equal to Term SOFR plus 0.10% plus an applicable margin, or an alternate base rate plus an applicable margin, where the alternate base rate is the greater of the prime rate, the federal funds effective rate plus 0.50%, and one-month Term SOFR plus 0.10% plus 1.00%. Term loan borrowings are being made at one-month Term SOFR. The applicable margin for the term benchmark borrowings ranges from 1.0% to 2.0%, and the applicable margin for alternate base rate borrowings ranges from 0% to 1.0%, in each case, based on the total net leverage ratio of the Company and its restricted subsidiaries. The Company may select interest periods of one, three or six months for Term SOFR borrowings. Interest is payable at the end of the selected interest period, but no less frequently than quarterly. The Company’s obligations under the Credit Agreement are guaranteed by its material domestic subsidiaries (each, a “Guarantor”), and secured by a first priority perfected security interest in substantially all of the existing and future personal property of the Company and each Guarantor, subject to certain exceptions. The collateral security described above also secures certain banking services obligations and interest rate swaps and currency or other hedging obligations of the Company owing to any of the then existing lenders or any affiliates thereof. Concurrently with the Company’s entry into the Credit Agreement, the Company also entered into a seven year interest rate swap agreement with Wells Fargo Bank, N.A., Co-Syndication Agent and lender under the Credit Agreement, on $100 million of borrowings under the Credit Agreement. The interest rate swap agreement matures in May 2029. Outstanding borrowings at March 31, 2023 under the Credit Agreement were $273 million, consisting of current borrowings of $57.6 million and long-term debt of $215.4 million; while outstanding borrowings at December 31, 2022 were $239.5 million, consisting of current borrowings of $55 million and long-term debt of $184.5 million. Letters of credit outstanding under the Credit Agreement were $2.4 million at both March 31, 2023 and December 31, 2022. At March 31, 2023, the weighted average interest rate under our Credit Agreement was 5.6%, which consisted of $273 million in borrowings under Term SOFR, adjusted for the impact of the interest rate swap agreement on $100 million of borrowings. At December 31, 2022, the weighted average interest rate under our Credit Agreement was 5.2%, which consisted of $237 million in borrowings at 5.2% under Term SOFR, adjusted for the impact of the interest rate swap agreement on $100 million of borrowings, and an alternative base rate borrowing of $2.5 million at 8%. During the three months ended March 31, 2023, our average daily alternative base rate loan balance was $0.3 million, compared to a balance of $2.6 million for the three months ended March 31, 2022 and a balance of $5.6 million for the year ended December 31, 2022. The Credit Agreement contains customary covenants limiting, among other things, the incurrence of additional indebtedness, the creation of liens, mergers, consolidations, liquidations and dissolutions, sales of assets, dividends and other payments in respect of equity interests, acquisitions, investments, loans and guarantees, subject, in each case, to customary exceptions, thresholds and baskets. The Credit Agreement also contains customary events of default. Polish Overdraft Facility In October 2022, our Polish subsidiary, SMP Poland sp. z.o.o., amended its overdraft facility with HSBC Continental Europe (Spolka Akcyjna) Oddzial w Polsce to provide for borrowings under the facility in Euros and U.S. Dollars. Under the amended terms, the overdraft facility provides for borrowings of up to Zloty 30 million (approximately $7 million) if borrowings are solely in Zloty, or up to 85% of the Zloty 30 million limit (approximately $5.9 million) if borrowings are in Euros and/or U.S. Dollars. The overdraft facility has an initial maturity date in December 2022, with automatic three-month renewals until June 2027, subject to cancellation by either party, at its sole discretion, at least 30 days prior to the commencement of the three-month renewal period. Borrowings under the amended overdraft facility will bear interest at a rate equal to (1) the one month Warsaw Interbank Offered Rate (“WIBOR”) + 1.5% for borrowings in Polish Zloty, (2) the one month Euro Interbank Offered Rate (“EURIBOR”) + 1.5% for borrowings in Euros, and (3) the Mid-Point of the Fed Target Range + 1.75% for borrowings in U.S Dollars. Borrowings under the overdraft facility are guaranteed by Standard Motor Products, Inc., the ultimate parent company. There were no borrowings outstanding under the overdraft facility at both March 31, 2023 and December 31, 2022.

Stock-Based Compensation Plans We account for our stock-based compensation plans in accordance with the provisions of FASB ASC 718, Stock Compensation Restricted and Performance Stock Grants We are authorized to issue, among other things, shares of restricted and performance-based stock to eligible employees and restricted stock to directors of up to shares under the Amended and Restated Omnibus Incentive Plan (“Plan”). As part of the Plan, we currently grant shares of restricted stock to eligible employees and our independent directors and performance-based shares to eligible employees. We grant eligible employees types of restricted stock (standard restricted shares and long-term retention restricted shares). Standard restricted shares granted to employees become fully vested no earlier than after the date of grant. Long-term retention restricted shares granted to selected executives vest at a rate on or within approximately of an executive reaching the ages 60 and 63 and become fully vested on or within approximately of an executive reaching the age 65 Restricted shares granted to directors become fully vested upon the first anniversary of the date of grant. Performance-based shares issued to eligible employees are subject to a three-year measuring period and the achievement of performance targets and, depending upon the achievement of such performance targets, they may become vested no earlier than three years after the date of grant. Each period we evaluate the probability of achieving the applicable targets, and we adjust our accrual accordingly.

Employee Benefits	Note 12. Employee Benefits We provide certain medical and dental care benefits to former U.S. union employees. We maintain a defined contribution Supplemental Executive Retirement Plan for key employees. Under the plan, these employees may elect to defer a portion of their compensation and, in addition, we may at our discretion make contributions to the plan on behalf of the employees. In March 2023, we made company contributions to the plan of $0.8 million related to calendar year 2022. We also have an Employee Stock Ownership Plan and Trust for employees who are not covered by a collective bargaining agreement. In connection therewith, we maintain an employee benefits trust to which we contribute shares of treasury stock. We are authorized to instruct the trustees to distribute such shares toward the satisfaction of our future obligations under the plan. The shares held in trust are not considered outstanding for purposes of calculating earnings per share until they are committed to be released. The trustees will vote the shares in accordance with their fiduciary duties. During the three months ended March 31, 2023 we contributed to the trust an additional shares from our treasury and released shares from the trust leaving shares remaining in the trust as of March 31, 2023.

Derivative Financial Instruments [Abstract]
Derivative Financial Instruments	Note 13. Derivative Financial Instruments Interest Rate Swap Agreements We occasionally use derivative financial instruments to reduce our market risk for changes in interest rates on our variable rate borrowings. The principal financial instruments used for cash flow hedging purposes are interest rate swap agreements. The interest rate swaps effectively convert a portion of our variable rate borrowings under our existing facilities to a fixed rate based upon determined notional amount. We do not enter into interest rate swap agreements, or other financial instruments, for trading or speculative purposes. In June 2022, we entered into a seven year interest rate swap agreement with a notional amount of $100 million that is to mature in May 2029 The fair value of the interest rate swap agreement as of March 31, 2023 and December 31, 2022 was an asset of $3.3 million and $5.2 million, respectively, which has been deferred and recorded in accumulated other comprehensive income, net of income taxes, in our consolidated balance sheet. When the interest expense on the underlying borrowing is recognized, the deferred gain/loss in accumulated other comprehensive income is recorded in earnings as interest expense in the consolidated statements of operations. We perform quarterly hedge effectiveness assessments and anticipate that the interest rate swap will be highly effective throughout its term.

Fair Value Measurements [Abstract]
Fair Value Measurements	Note 14. Fair Value Measurements We follow a three-level fair value hierarchy that prioritizes the inputs to measure fair value. This hierarchy requires entities to maximize the use of “observable inputs” and minimize the use of “unobservable inputs.” The three levels of inputs used to measure fair value are as follows: Level 1: Quoted prices (unadjusted) for identical assets or liabilities in active markets as of the measurement date. Level 2: Significant other observable inputs other than Level 1 prices such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data. Level 3: Significant unobservable inputs that reflect assumptions that market participants would use in pricing an asset or liability. The following is a summary of the estimated fair values, carrying amounts, and classification under the fair value hierarchy of our financial instruments at March 31, 2023 and December 31, 2022 (in thousands): March 31, 2023 December 31, 2022 Fair Value Hierarchy Fair Value Carrying Amount Fair Value Carrying Amount Cash and cash equivalents LEVEL 1 $ 24,196 $ 24,196 $ 21,150 $ 21,150 Deferred compensation LEVEL 1 22,410 22,410 20,190 20,190 Short term borrowings LEVEL 1 57,614 57,614 55,031 55,031 Long-term debt LEVEL 1 215,487 215,487 184,589 184,589 Cash flow interest rate swap LEVEL 2 3,311 3,311 5,174 5,174 The carrying value of cash and cash equivalents approximates fair value due to the short maturity of those investments. The fair value of the underlying assets held by the deferred compensation plan are based on the quoted market prices of the underlying funds which are held by registered investment companies. The carrying value of our variable rate short-term borrowings and long-term debt under our credit facilities approximates fair value as the variable interest rates in the facilities reflect current market rates. The fair value of our cash flow interest rate swap obtained from two independent third parties, is based upon market quotes, and represents the net amount required to terminate the interest rate swap, taking into consideration market rates and counterparty credit risk.

Commitments and Contingencies [Abstract]
Commitments and Contingencies	Note 18. Commitments and Contingencies Asbestos In 1986, we acquired a brake business, which we subsequently sold in March 1998 and which is accounted for as a discontinued operation in the accompanying statement of operations. When we originally acquired this brake business, we assumed future liabilities relating to any alleged exposure to asbestos-containing products manufactured by the seller of the acquired brake business. In accordance with the related purchase agreement, we agreed to assume the liabilities for all new claims filed on or after September 2001. Our ultimate exposure will depend upon the number of claims filed against us on or after September 2001, and the amounts paid for settlements, awards of asbestos-related damages, and defense of such claims. At March 31, 2023, approximately 1,485 cases were outstanding for which we may be responsible for any related liabilities. Since inception in September 2001 through March 31, 2023, the amounts paid for settled claims and awards of asbestos-related damages, including interest, were approximately $67 million. We do not have insurance coverage for the indemnity and defense costs associated with the claims we face. In evaluating our potential asbestos-related liability, we have considered various factors including, among other things, an actuarial study of the asbestos related liabilities performed by an independent actuarial firm, our settlement amounts and whether there are any co-defendants, the jurisdiction in which lawsuits are filed, and the status and results of such claims. As is our accounting policy, we consider the advice of actuarial consultants with experience in assessing asbestos-related liabilities to estimate our potential claim liability; and perform an actuarial evaluation in the third quarter of each year and whenever events or changes in circumstances indicate that additional provisions may be necessary. The methodology used to project asbestos-related liabilities and costs in our actuarial study considered: (1) historical data available from publicly available studies; (2) an analysis of our recent claims history to estimate likely filing rates into the future; (3) an analysis of our currently pending claims; (4) an analysis of our settlements and awards of asbestos-related damages to date; and (5) an analysis of closed claims with pay ratios and lag patterns in order to develop average future settlement values. Based on the information contained in the actuarial study and all other available information considered by us, we have concluded that no amount within the range of settlement payments and awards of asbestos-related damages was more likely than any other and, therefore, in assessing our asbestos liability we compare the low end of the range to our recorded liability to determine if an adjustment is required. In accordance with our policy to perform an annual actuarial evaluation in the third quarter of each year, an actuarial study was performed as of August 31, 2022. The results of the August 31, 2022 study included an estimate of our undiscounted liability for settlement payments and awards of asbestos-related damages, excluding legal costs, ranging from $68.8 million to $111.6 million for the period through 2065. The change from the prior year study, which was as of August 31, 2021, was a $7.9 million increase for the low end of the range and a $11.4 million increase for the high end of the range. The increase in the estimated undiscounted liability from the prior year study at both the low end and high end of the range reflects our actual experience, our historical data and certain assumptions with respect to events that may occur in the future. Based upon the results of the August 31, 2022 actuarial study, in September 2022 we increased our asbestos liability to $68.8 million, the low end of the range, and recorded an incremental pre-tax provision of $18.5 million in earnings (loss) from discontinued operations in the accompanying statement of operations. Future legal costs, which are expensed as incurred and reported in earnings (loss) from discontinued operations in the accompanying statement of operations, are estimated, according to the August 31, 2022 study, to range from $53.2 million to $105.7 million for the period through 2065. Total operating cash outflows related to discontinued operations, which include settlements, awards of asbestos-related damages and legal costs, net of taxes, were $2.6 million and $5 million for the three months ended March 31, 2023 and 2022, respectively. We plan to perform an annual actuarial evaluation during the third quarter of each year for the foreseeable future and whenever events or changes in circumstances indicate that additional provisions may be necessary. Given the uncertainties associated with projecting such matters into the future and other factors outside our control, we can give no assurance that additional provisions will not be required. We will continue to monitor events and changes in circumstances surrounding these potential liabilities in determining whether to perform additional actuarial evaluations and whether additional provisions may be necessary. At the present time, however, we do not believe that any additional provisions would be reasonably likely to have a material adverse effect on our liquidity or consolidated financial position. Other Litigation We are currently involved in various other legal claims and legal proceedings (some of which may involve substantial amounts), including claims related to commercial disputes, product liability, employment, and environmental. Although these legal claims and legal proceedings are subject to inherent uncertainties, based on our understanding and evaluation of the relevant facts and circumstances, we believe that the ultimate outcome of these matters will not, either individually or in the aggregate, have a material adverse effect on our business, financial condition or results of operations. We may at any time determine that settling any of these matters is in our best interests, which settlement may include substantial payments. Although we cannot currently predict the specific amount of any liability that may ultimately arise with respect to any of these matters, we will record provisions when the liability is considered probable and reasonably estimable. Significant judgment is required in both the determination of probability and the determination as to whether an exposure can be reasonably estimated. As additional information becomes available, we reassess our potential liability related to these matters. Such revisions of the potential liabilities could have a material adverse effect on our business, financial condition or results of operations. Warranties We generally warrant our products against certain manufacturing and other defects. These product warranties are provided for specific periods of time of the product depending on the nature of the product. As of March 31, 2023 and 2022, we have accrued $20.6 million and $20.7 million, respectively, for estimated product warranty claims included in accrued customer returns. The accrued product warranty costs are based primarily on historical experience of actual warranty claims. The following table provides the changes in our product warranties (in thousands): Three Months Ended March 31, 2023 2022 Balance, beginning of period $ 19,667 $ 17,463 Liabilities accrued for current year sales 25,793 22,626 Settlements of warranty claims (24,860 ) (19,378 ) Balance, end of period $ 20,600 $ 20,711

Basis of Presentation [Abstract]
Principles of Consolidation	Standard Motor Products, Inc. and its subsidiaries (referred to hereinafter in these notes to the consolidated financial statements as “we,” “us,” “our,” “SMP,” or the “Company”) is a leading manufacturer and distributor of premium replacement parts in the automotive aftermarket, and custom-engineered solutions for vehicle control and thermal management categories in diversified end markets. We sell our products primarily to automotive aftermarket retailers, warehouse distributors, original equipment manufacturers and original equipment service part operations in the United States, Canada, Europe, Asia, Mexico and other Latin American countries. The accompanying unaudited financial information should be read in conjunction with the audited consolidated financial statements and the notes thereto included in our Annual Report on Form -K for the year ended December The unaudited consolidated financial statements include our accounts and all domestic and international companies in which we have more than a equity ownership, except in instances where the minority shareholder maintains substantive participating rights, in which case we follow the equity method of accounting. In instances where we have more than a equity ownership and the minority shareholder does not maintain substantive participating rights, our consolidated financial statements include the accounts of the company on a consolidated basis with its net income and equity reported at amounts attributable to both our equity position and that of the noncontrolling interest. Investments in unconsolidated affiliates are accounted for on the equity method, as we do not have a controlling financial interest but have the ability to exercise significant influence. All significant inter-company items have been eliminated. The accompanying unaudited consolidated financial statements have been prepared in accordance with generally accepted accounting principles for interim financial information and with the instructions to Form -Q and Rule - of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by generally accepted accounting principles for complete financial statements. In the opinion of management, all adjustments (consisting of normal recurring adjustments) considered necessary for a fair presentation have been included. The results of operations for the interim periods are not necessarily indicative of the results of operations for the entire year.
Reclassification	Reclassification Certain prior period amounts in the accompanying consolidated financial statements and related notes have been reclassified to conform to the 2023 presentation.
Reportable Segments	Reportable Segments Beginning on January 1, 2023, we reorganized our business into three operating segments – Engineered Solutions, Vehicle Control and Temperature Control. The new operating segment structure provides clarity regarding the unique dynamics and margin profiles of the markets served by each segment, better aligns our operating segments with our strategic focus on diversification, and provides greater transparency into our positioning to capture growth opportunities in the future. Prior period segment results have been reclassified to conform to our operating segment reorganization. For additional information related to our segment reorganization, see Note 7, “Goodwill and Acquired Intangible Assets,” Note 16, “Industry Segments,” and Note 17, “Net Sales.”
