FEULING PARTS BA Series Air Cleaner Kit for Gen 1 M8

Unlock impressive horsepower and torque gains with this high-performance air cleaner kit, engineered to deliver exceptional results on stock engines and even bigger gains on builds with modified/ported cylinder heads, upgraded intakes, and larger throttle bodies. Developed on the flow bench, dyno-tested, and track proven, it’s designed to maximize airflow, throttle response, and overall engine efficiency.

The streamlined one-piece design creates a clean look and simplifies installation compared to typical multi-piece stack-up constructions. Lengthened intake runners increase air velocity and deliver added volume for a balanced, dynamic flow, while the high-flow billet aluminum velocity stack features an optimized opening diameter, outer lip, and internal (ID) taper to promote smooth, efficient airflow into the engine.

Out of the box, it’s configured with OEM-style cylinder head breathing, routing into the intake through optimized vent hole locations to support emissions standards. For performance-focused setups, the convertible backing plate provides optional cylinder head venting flexibility. Each kit includes a high-flow, washable/reusable 2.5" wide air filter paired with a one-piece billet cage for durability and consistent filtration. Made in the USA.
