FEULING OIL PUMP CORP. BA Air Cleaner Kit - Black with Black Filter - M8 5573

If you're running a stock intake setup, you're leaving horsepower on the table. The FEULING BA Air Cleaner Kit uses flow-bench engineering and dyno-proven design to increase air velocity and volume through optimized intake runners, delivering measurable gains across the RPM band. On modified engines with ported heads and larger throttle bodies, the performance advantage becomes even more pronounced.

Built from high-flow billet aluminum with a precision velocity stack, this bolt-on kit combines aggressive performance with a clean, finished look. The reusable high-flow filter saves you money long-term while the convertible backing plate lets you choose between OEM-compliant emissions routing or optional cylinder head venting—giving you flexibility based on your setup and local regulations.
