TC Bros. Finned Air Cleaner for Harley-Davidson CV Carburetors and EFI Throttle Bodies

Looking for a compact, high-quality replacement for the your factory-style air cleaner? Show off a little bit more of your engine with this TC Bros. finned air cleaner kit.

  • Compact design to put your engine on display
  • Available in three finishes
  • 356-T6 aluminum cover
  • High-performance air filter element is washable and reusable
  • Cast finned design is timeless and works on a variety of build styles
  • For Big Twin and Sportster
  • Made in USA

The kit features a CNC-machined, powder coated steel mounting bracket that is proudly made in the USA. Included mounting hardware is recessed to provide proper sealing surface for the included high-flow filter element, which is reusable and designed specifically to provide the appropriate amount of air for this air cleaner assembly.

This ultra-compact kit is designed to fit most Harley-Davidson Big Twin and Sportster models using factory CV carburetors or factory electronic fuel injection (EFI) throttle bodies; please see fitment notes for more detail. 

When replacing a factory air cleaner on carbureted models, it is imperative that the carburetor be supported; we recommend the use of a TC Bros. support bracket or equivalent. Provisions for breathing must be made for later motorcycles that use cylinder head breathers; we recommend our breather bolt kits or an equivalent. Not legal for sale or use in California. 

Tuning is recommended for all applications; this includes rejetting carburetors or altering fuel maps for fuel injected motorcycles to account for the increased airflow.

  • 1988-2022 Harley-Davidson Sportster equipped with Evolution (air-cooled) engine; all 1991-and-newer Sportsters will require cylinder head breather bolts; 1988-and newer carbureted Sportsters will also require a carburetor support bracket
