4" Air Cleaner Assembly

These AC assemblies are all 6061 AL and come with a washable reusable filter element. The bases are turned and milled from one solid piece and the threaded hole for the cover is at the top, NOT at the bottom to block your air flow like a lot of our competitors. We currently make these for Keihin CV, Mikuni HSR42, S&S Super E/G and B and Bendix Zenith. Because of the time consuming nature of making these we only make these once the order is placed. When placing an order, please note the cover you want by its location in the picture, ie. 1A, 3C etc...
