With years of experience designing improved cylinder heads, combustion chambers and intake manifolds, FEULING brings light to a new bolt-on air cleaner design for Harley-Davidson motorcycles. The Feuling BA air cleaner lengthens the intake runners and increases air velocity, delivering added volume for balanced dynamic flow.

The BA air cleaner features a highflow billet aluminum velocity stack with optimal opening diameter, outer lip and internal (ID) taper. The BA Air Cleaner includes a highflow reusable air filter and one piece billet cage. The one piece design, creates a clean look and eases installation when compared to the industry standard multi stack up construction.

With performance in mind, we created a convertible backing plate offering optional cylinder head venting. Out of the box, the FEULING air cleaner is set up with OEM - style cylinder head breathing, routing into the intake with optimized vent hole locations to meet emissions standards. External Race Only venting to atmosphere available with separate purchase of kit #5417 which includes fittings, vent line and breather element. The backing plate is engraved with both MADE IN USA and FEULING logos.

Impressive Horsepower and Torque gains on any engine and exceptional gains seen on engines running modified and/or ported cylinder heads along with intakes and larger throttle bodies. Developed and designed on the flow bench, dyno tested and track proven.
