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.
A great deal of meticulous testing and tuning went into the design of the direct-mount BA (Billet Aluminium) air filter, to create excellent performance (+500 to 595 CFM@28 on a SuperFlow SF600), all paired with the smallest possible dimensions. One-piece full billet 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 path and increase intake velocity to improve cylinder charging, especially mid-range performance, where most riding is done, and upward. Comes with a reusable high-flow, cotton-based, red, pre-oiled air filter element.
Note: The optional covers are available in natural polished, hard anodised black and chrome finishes, with a solid or transparent (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 shorter 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 enhanced cylinder heads, combustion chambers and 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 machined 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 machined aluminium cage. The one-piece design creates a clean look and makes installation easier compared with the industry standard multi-piece construction.
With performance in mind, we created a convertible backplate offering optional cylinder head breathing. From the factory, the FEULING air filter is configured with OEM-style head breathing, channelling into the intake with optimised vent hole locations to meet emissions regulations. External "Race Only" venting to the atmosphere is 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 using modified and/or ported cylinder heads together with larger intakes and throttle bodies. Developed and designed on the flow bench, proven on the dynamometer and demonstrated on the track.
Maximum flow: 595 CFM AT 28".
MADE IN THE USA. Note: Product available on special order only.
