This new line of air cleaners was created to perfectly match our popular classic aluminum finned valve covers. Gives you plenty of options for that "just right" look on any nostalgia rod or muscle car. The small oval air cleaner provides adequate hood clearance in demanding applications as well as a coordinated appearance with the classic finned look. They come with a medical grade, pre-oiled cotton gauze element for excellent filtration. Works with all popular 5 1/8" necks, for all carburetors or throttle bodies.
