A great deal of meticulous testing and tuning went into the direct-mount BA (machined aluminium air filter) design, to create excellent performance, all combined with the smallest possible dimensions. One-piece full machined 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-based air filter element.
Note: The optional covers are available in polished raw aluminium, hard anodized black and chrome, with a solid or clear acrylic outer cover (clear).
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 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 CNC-machined aluminium velocity stack with optimal opening diameter, outer lip and inner cone (ID). The BA Air Filter includes a reusable high-flow air filter and a one-piece CNC-machined aluminium 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 that offers optional cylinder head ventilation. From the factory, the FEULING air filter is configured with OEM-style cylinder head breathing, venting to 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.
