FEULING PARTS BA Air Cleaner Kit — 2.5" wide filter, Round, Black – 25-26 Softail, 24-25 Touring, 23-26 CVO, 26 Trike

The BA Air Cleaner Kit features lengthened intake runners to increase air velocity and deliver added volume for a balanced, dynamic flow. 🚀

Its one-piece design creates a clean look and simplifies installation compared with standard multi-stack constructions.

A high-flow billet aluminum velocity stack with optimized opening diameter, outer lip and internal taper refines airflow and improves throttle response.

The kit includes a washable, reusable 2.5" wide high-flow filter in a one-piece cage, delivering impressive horsepower and torque gains—especially on engines with modified or ported heads and larger throttle bodies.

Developed on the flow bench, dyno tested and track proven, this unit ships configured for OEM-style cylinder head breathing; external race-only venting is available separately. Made in the USA.
