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

The backplate is etched with the 'Made in USA' and 'Feuling' logos.
Many meticulous tests and adjustments went into the design of the direct-mount BA (forged aluminium air filter), to create excellent performance, all paired 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 filling, especially mid-range performance, where most riding is done, and upward. Comes with a reusable high-flow pre-oiled red cotton air filter element.
Note: The optional covers are available in raw polished, hard black anodised and chrome finishes, 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 stands 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 filter features a high-flow forged aluminium velocity stack with optimum opening diameter, outer lip and inner cone (ID). The BA Air Filter 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 head ventilation. From the factory, the FEULING air filter is configured with OEM style head breathing, channelling into the intake with optimised vent hole locations to comply with emissions regulations. External "Race Only" venting to the atmosphere available with the separate purchase of kit #5417, which includes fittings, vent line and breather element. The backplate is etched 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 milled heads along with larger intakes and throttle bodies. Developed and designed on the flow bench, dyno tested and proven on the track.
MADE IN THE USA.
