12" Polished Aluminum Center Finned Air Cleaner Top

• Center-finned polished aluminum top with distinct machined pattern

• Top only — pairs with a compatible base and filter for a full assembly

• Fits any 12" x 8 3/8" oval air-cleaner housing — match base and stud

• 5.65" tapered Allen head stud included

This center-finned polished aluminum top is designed for 12" x 8 3/8" oval air-cleaner assemblies, giving a clean polished appearance with a distinctive machined-pattern finish and serviceable fitment. It's built as a top-only component, so it requires a separately purchased compatible base and filter element to form a complete air-cleaner assembly.

Aluminum construction with a polished finish supports long-term engine-bay appearance and durability. The stud is 5.65" with a tapered Allen head. Before ordering, verify top diameter, stud size, and base compatibility, and match this top with a compatible base, filter height, carburetor neck, and hood clearance for final assembly.

Useful for street performance and restoration builds assembling a custom air-cleaner combination, or for replacing a damaged or mismatched top on an existing 12" oval air-cleaner assembly without buying a full new kit.

Applications
Fits 12" x 8 3/8" oval air-cleaner assemblies; useful for custom air-cleaner builds or replacing a damaged/mismatched top on an existing assembly.

Sizing
12" x 8 3/8" oval, center-finned top style, polished aluminum finish, 5.65" tapered Allen head stud. Top only — requires a separately purchased compatible base and filter element.

Does this include the base and filter, or just the top?
This listing is for the air cleaner top only. A compatible base and filter element must be purchased separately to complete the air cleaner assembly.

Will this fit any 12" oval air-cleaner base?
Not necessarily. Verify the top size, center stud, and sealing surface are compatible with your existing 12-inch oval air cleaner base before ordering.

What size stud does this top use?
This air cleaner top uses a 5.65-inch tapered Allen-head stud.

Is this the same top used on the 12" oval kits sold elsewhere in this catalog?
This top shares the same 12-inch × 8⅜-inch oval dimensions and 5.65-inch tapered Allen-head stud specification as several complete kits in this product line. Verify compatibility with your specific base before purchasing separately.

Why would I buy just the top instead of a full kit?
A top-only listing is ideal for replacing a damaged or worn air cleaner lid or for building a custom air cleaner assembly using your preferred base, filter element, and top.
