The beauty of simple 8" air filter is now available from Model Behavior for a single or dual quad setup. Modeled after factory units, this filter will clear your hood and will fit any of our 4150 based Holley carburetors with a 5.125” flange opening, just like the real version. They have filter detail on both sides, lid, base, and filter are all printed separately, and all lids have a center hole for a mounting stud that you supply.
