Check the appropriate box below if the Form 8-K filing is intended to simultaneously satisfy the filing obligation of the registrant under any of the following provisions (see General Instruction A.2. below):

On September 23, 2010, United Components Inc. (the “Company”), UCI International, Inc., the indirect parent entity of the Company (“UCI”) and UCI Acquisition Holdings, Inc., a wholly-owned subsidiary of UCI and direct parent entity of the Company (“Holdings”), entered into a Credit Agreement, between the Company, as borrower, UCI and Holdings, as guarantors, Bank of America, N.A., as administrative agent, Banc of America Securities LLC and Deutsche Bank Securities Inc., as joint lead arrangers and joint bookrunners, Deutsche Bank Securities Inc., as syndication agent and General Electric Capital Corporation and Keybank, N.A., as co-documentation agents (the “Credit Agreement”).

The Credit Agreement provides for borrowings of up to $500.0 million, which consists of a term loan facility in an aggregate principal amount of $425.0 million, which was fully funded on the date of the Credit Agreement, and a revolving credit facility in an aggregate principal amount of $75.0 million, none of which was drawn on the date of the Credit Agreement. The total amount of the $75.0 million revolving credit facility available for borrowing at September 23, 2010 was approximately $23.1 million due to certain restrictions under the UCI’s floating rate senior PIK notes. The maturity date for the (i) term loan facility is 6.5 years from the date of the Credit Agreement and (ii) revolving credit facility is 5 years from the date of the Credit Agreement.

The interest rates payable under the Credit Agreement will depend on the type of loan plus an applicable margin. The initial applicable margin of any Eurodollar Rate Loans made under the Credit Agreement equals 4.50% and the initial applicable margin for any Base Rate Loans made under the Credit Agreement equals 3.50% with step downs of 0.50% for every fiscal quarter after the first full fiscal quarter ending after the closing date for which the total leverage ratio is equal to or less than 3.00 to 1.00. A commitment fee of 0.75% per annum accrues on unused amounts of the commitments under the revolving credit facility with step downs to 0.50% for every fiscal quarter after the first full fiscal quarter ending after the closing date for which the total leverage ratio is equal to or less than 3.00 to 1.00.

The Credit Agreement contains customary representations and warranties and covenants, including, without limitation, the following covenants: maintenance of a maximum total leverage ratio, maintenance of minimum interest coverage ratio and maximum capital expenditures covenant.

The Credit Agreement also includes customary events of default, in certain cases subject to reasonable and customary periods to cure, including but not limited to: failure to make payments when due, breach of covenants, breach of representations and warranties, insolvency proceedings, certain judgments and attachments and any change of control. The occurrence of an event of default may result in the termination of the Credit Agreement, accelerate the Company’s repayment obligations and allow the loan parties to exercise all rights and remedies available to them with respect to the collateral. Certain defaults under the financial maintenance covenants may be cured by equity contributions to the Company, subject to customary limitations on the amount of equity contributions, the use of proceeds thereof and the number of times on which the cure may be utilized.

Pursuant to a guarantee and collateral agreement, dated September 23, 2010, by the Company, UCI, Holdings and the wholly-owned restricted, material subsidiaries of the Company, as guarantors in favor of the administrative agent for the benefit of the secured parties (the “Guarantee & Collateral Agreement”), all borrowings under the Credit Agreement are secured by (subject to certain exceptions) a (i) first priority security interest in and mortgages on substantially all tangible and intangible assets (including, without limitation, accounts receivable, inventory, equipment, general intangibles, intercompany notes, insurance policies, investment property, intellectual property, material owned real property and proceeds of the foregoing) and (ii) first-priority security interest in (A) 100% of the stock of Holdings and the Company and 100% of the stock of substantially all of the Company’s present and future direct and indirect restricted domestic subsidiaries (other than any restricted domestic subsidiary substantially all of the assets of which constitute the equity of controlled foreign corporations (each, a “CFC Holdco”)), (B) 100% of the non-voting stock of substantially all of the Company’s first-tier present and future foreign subsidiaries and (C) 65% of the voting stock of substantially all of the Company’s first-tier present and future foreign subsidiaries and CFC Holdcos.

The foregoing descriptions of the Credit Agreement and Guarantee & Collateral Agreement are qualified in their entirety by the terms of each such agreement, copies of which are filed as Exhibits 10.1 and 10.2, respectively, to this Current Report and incorporated herein by reference.

In connection with the entry by the Company into the Credit Agreement described under Item 1.01, on September 23, 2010, the Company’s Amended and Restated Credit Agreement, dated May 25, 2006 (the “Previous Credit Agreement”), by and among the Company, as borrower, Lehman Brothers Inc. and J.P. Morgan Securities Inc., as joint advisors, joint lead arrangers and joint bookrunners, JPMorgan Chase Bank, N.A., as syndication agent, ABN AMRO Bank N.V., Bank of America, N.A. and General Electric Capital Corporation, as co-documentation agents, and Bank of America, N.A. (as successor to Lehman Commercial Paper Inc.), as administrative agent, and the several banks and other financial institutions or entities from time to time parties to the agreement, was terminated and all obligations existing under the Previous Credit Agreement were repaid in full using a portion of the proceeds of the Credit Agreement. The Previous Credit Agreement was scheduled to expire on June 30, 2012; there were no penalties for early termination. As a result of the termination of the Previous Credit Agreement, the Guarantee and Collateral Agreement, dated as of June 20, 2003, among the Company, Holdings and certain subsidiaries of the Company, for the benefit of Lehman Commercial Paper, Inc., as administrative agent, was terminated as well.
