FEULING OIL PUMP CORP. BA Race Series Air Cleaner Kit - Raw - Black Filter 5521

If you're running a modified Harley-Davidson engine with ported heads, an oversized intake, or a larger throttle body, your stock air cleaner is choking your potential. The Feuling BA Race Series Air Cleaner delivers a 33% larger filter element and optimized intake runner geometry to unlock the airflow your engine needs for meaningful horsepower and torque gains. Built as a single-piece billet design, it installs cleanly and bolts on without the complexity of multi-stack construction.

Purpose-engineered for the 130cc Bagger GP race platform, this kit prioritizes dynamic flow balance through lengthened intake runners, velocity stacking geometry, and strategically positioned vent holes that work with OEM-style cylinder head breathing. The result is added air volume where it counts—especially on engines with significant head and intake modifications.
