FEULING OIL PUMP CORP. BA Air Cleaner Kit - Black/Clear with Black Filter - Twin Cam 5544

If you're running a stock intake manifold, you're leaving horsepower on the table. The Feuling BA Air Cleaner Kit combines extended intake runners with a high-flow velocity stack to increase air velocity and deliver measurable power gains across the RPM band. Whether you're bolting this onto a stock Twin Cam or a heavily modified engine with ported heads, you'll see real results on the dyno and feel them on the road or track.

This is flow-bench engineered, dyno-tested, and track-proven hardware—not theoretical marketing. The billet aluminum velocity stack features an optimized opening diameter and internal taper designed to accelerate intake charge velocity while the reusable high-flow filter eliminates disposable waste. The convertible backing plate lets you choose between OEM-style cylinder head breathing or optional venting, giving you flexibility to tune breathing characteristics to your specific build. Every unit is made in the USA and proudly engraved with Feuling branding.
