From the factory, this Feuling air filter is configured with OEM-style head breathing, channelling into the intake with optimised vent hole locations to comply with emissions regulations.

The backplate is engraved with the 'Made in USA' and 'Feuling' logos.
A great deal of testing and meticulous tuning went into the direct-mount BA (forged aluminium air filter) design, to create excellent performance, all combined with the smallest possible dimensions. One-piece full forged aluminium cage, the included velocity stack is inserted, followed by the air filter element, after which the cover is fitted. This simple construction offers a very clean look and easy installation compared to many others. The velocity stack is used to lengthen the intake tract and increase intake velocity to improve cylinder charging, especially mid-range performance, where most riding is done, and upwards. Comes with a reusable, high-flow, red cotton air filter element, pre-oiled.
Note: The optional covers are available in untreated polished aluminium, hard anodised black and chrome, with a solid or clear (see-through) acrylic outer cover.
Originally designed for our 130" Bagger GP race engine, what is now our Race Series (RS) BA air filter, measures just one inch taller and boasts an impressive 33% increase in filter size compared to our standard fit BA air filter. NOTE: Requires mid-foot controls.
With years of experience designing cylinder heads, combustion chambers and improved intake manifolds, FEULING introduces a new direct-mount air filter design for Harley-Davidson motorcycles. The Feuling BA Air Filter lengthens the intake runners and increases air velocity, delivering additional volume for balanced dynamic flow.
The BA air cleaner features a high-flow forged aluminium velocity bell with optimal opening diameter, outer lip and inner cone (ID). The BA Air Cleaner includes a reusable high-flow air filter and a one-piece forged cage. The one-piece design creates a clean look and makes installation easier compared to the industry standard multi-stack construction.
With performance in mind, we created a convertible backplate offering optional crankcase ventilation. As shipped, the FEULING air filter is configured with OEM-style crankcase breathing, venting into the intake with optimised vent hole locations to comply with emissions regulations. External 'Race Only' venting to the atmosphere is available with the separate purchase of kit #5417, which includes fittings, vent line and filter element. The backplate is engraved with the 'MADE IN USA' and 'FEULING' logos.
Impressive Horsepower and Torque gains on any engine and exceptional gains seen on engines with modified and/or ported heads alongside larger intakes and throttle bodies. Developed and designed on the flow bench, dyno tested and proven on the track.
MADE IN THE USA.
