Spectre 14 inch outside-diameter 3 inch tall chrome air cleaner assemblies come with a flame retardant paper air filter and a reducer base plate. We offer this assembly with a chrome plated smooth lid. The recessed base allows for taller filter elements gaining greater air volume while still allowing for hood clearance. This air cleaner has been engineered to fit throttle body injection assemblies and carburetors with a 5-1/8 inch neck flange.
