FEULING OIL PUMP CORP. BA Race Series Air Cleaner Kit - Black Anodized - Black Filter 5523

If you're running a modified Harley-Davidson with ported heads, a larger throttle body, or an upgraded intake, your engine is starving for air. The Feuling BA Race Series Air Cleaner delivers 33% more filter surface area than standard units, lengthening intake runners and accelerating air velocity to feed your engine the volume it demands. This bolt-on upgrade translates to measurable horsepower and torque gains, especially on engines already optimized for performance.

Built from billet aluminum with a single-piece design, this air cleaner eliminates the multi-stack complexity of traditional assemblies while maintaining factory-style cylinder head breathing with precisely engineered vent locations. The high-flow washable filter and velocity stack are engineered for dynamic flow balance—meaning you get real power without compromise.
