Add classic vintage style to your motorcycle with these TC Bros. Choppers air cleaners in raw cast, black or polished finish. The covers are beautifully hand cast from 356-T6 aluminum right here in the USA. A washable cotton gauze filter element provides high performance air flow to your V-Twin. Kits attach easily using the American made, CNC machined, powder coated steel mounting bracket. These ultra-compact kits are designed to fit all Harley Davidson® Big Twin and Sportster models using factory CV Carburetors or factory electronic fuel injection (EFI) units. They will not fit '95-01 HD Big Twin models equipped with Magneti Marelli fuel injection units using dual bore throttle bodies. If installing on models using a CV carburetor, it is highly recommended to use in conjunction with a support bracket for longevity. Support bracket is not required on EFI models. Note: EVO Big Twins and '91-up Sportsters also require crankcase breathers.
