12" Polished Aluminum Ball Milled Oval Air Cleaner Kit with Flat Base

• Ball-milled aluminum top adds a machined, dressed-up look

• Flat base and ball-milled 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 ball-milled aluminum air cleaner adds a machined, dressed-up look to the engine bay, and this 12" x 8 3/8" oval kit pairs a flat base and ball-milled polished top with a white paper filter element sized for a 5 1/8" carburetor neck. Built for street performance builds, muscle car and hot rod restorations, and any carburetor swap looking for a machined polished aluminum finish.

The kit includes a white paper filter element (2" height), flat base, ball-milled polished 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 1/8", 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 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.

What's the difference between the smooth-top and ball-milled versions of this kit?
This version features a ball-milled machined aluminum top, while the standard version has a smooth aluminum top. Both share the same 12-inch × 8⅜-inch oval footprint, flat base, and white paper filter element.

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 3⅛ 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.

Is the ball-milled finish raw aluminum or coated?
This air cleaner kit is manufactured from polished aluminum with a machined ball-milled pattern. It is not painted or coated, and the finish can be maintained with regular aluminum polishing products.
