With years of experience designing improved cylinder heads, ports, combustion chambers and intake manifolds, brings light to a new bolt-on air cleaner design for Harley-Davidson motorcycles. The Feuling BA air cleaner lengthens the intake and delivers increased velocity and volume into the intake track.

The BA air cleaner features a high flow billet aluminum velocity stack with optimal opening and internal (ID) taper down to a direct match of the throttle body. The velocity stack is wrapped in a highflow air filter and encased with a one piece billet cage. The backing plate is setup with optimized breather vent locations and uses the standard cylinder head breathers. Engraved logos including MADE IN USA and FEULING give the final touch.
