12" Aluminum Finned Oval Air Cleaner Kit with Flat Base - Polished

• Finned polished aluminum top adds a classic, dressed-up look

• Flat base and finned top pair with a white paper filter element

• Fits any 5 1/8" carburetor neck — verify height/hood clearance first

• Includes mounting nut and stud — filter and base included in kit

A finned aluminum air cleaner is one of the most recognizable upgrades in the engine bay, and this 12" x 8 3/8" oval kit pairs a flat base and finned polished top with a white paper filter element sized for a 5 1/8" carburetor neck. Built for street performance and restoration applications running a 5 1/8" carburetor neck.

The kit includes a white paper filter element (2" height), flat base, finned polished aluminum top, and mounting nut and stud — everything needed to complete the air-cleaner assembly. This is a disposable filter, replaced rather than cleaned.

Overall assembled height is 3 3/8", with a 5 1/8" neck flange. Before installing, confirm your carburetor neck diameter, filter height, and hood clearance match this kit's dimensions, and check stud length, breather provisions, and fuel-line clearance for final assembly.

Is this the polished or black version of this kit?
This listing (SP6498) is the polished finish version. A black-finish version of this same finned air cleaner kit is available as a separate listing.

Is the filter in this kit washable or disposable?
This kit includes a white paper filter element, which is disposable. Replace the filter during routine maintenance rather than cleaning and reusing it.

Will this fit a Holley or Edelbrock carburetor?
Yes. This air cleaner kit fits carburetors with a 5⅛-inch neck (air horn) diameter, including many Holley and Edelbrock models. Verify your carburetor's neck size before ordering.

How much hood clearance do I need for this air cleaner?
This air cleaner has an overall assembled height of 3⅜ inches. Measure from the carburetor mounting flange to the underside of the closed hood to ensure adequate clearance before installation.

Does this kit include the mounting hardware?
Yes. This kit includes both a mounting stud and mounting nut for installation.

What's the difference between this and the ball-milled or smooth-top 12" kits?
This version features a finned aluminum top, while the other 12-inch oval kits use either a smooth or ball-milled top. All share the same 12-inch × 8⅜-inch oval footprint, white paper filter element, and overall fitment, differing primarily in top design and appearance.
