FEULING OIL PUMP CORP. BA Air Cleaner Kit - Black/Clear with Black Filter - '93-'99 Evolution Big Twin 5564

If you're running stock breathing on your Evolution Big Twin, you're leaving power on the table. The FEULING BA Air Cleaner Kit delivers measurable horsepower and torque gains by optimizing intake velocity and air volume—gains that become even more dramatic on modified or ported heads. Flow bench developed and dyno proven, this kit transforms your intake path from a restriction into a precision breathing system.

Built around a high-flow billet aluminum velocity stack with engineered taper geometry, the BA cleaner extends your intake runners while maintaining the dynamic balance your engine needs for responsive power delivery across the RPM range. The reusable high-flow filter keeps costs down without compromising filtration or airflow. Whether you're street riding or track testing, this is legitimate bolt-on performance that works.
