Feuling Parts Slim BA Air Cleaner Kit — BA Series, Black, Red

The Slim BA Air Cleaner Kit reduces right-side leg interference with a slimmer, one-piece cage that also delivers a clean, integrated look.

The slim cage measures 2.375 in high, improving rider fit without sacrificing intake area.

Developed on the flow bench and proven on the dyno and track, the design yields impressive horsepower and torque gains, especially on engines with modified heads and larger throttle bodies.

One-piece construction and lengthened intake runners increase air velocity and provide balanced dynamic flow for enhanced midrange performance.

A high-flow, washable/reusable filter works with a precision-machined aluminum velocity stack engineered for optimal opening diameter and internal taper.

Installation is simplified compared with multi-stack designs, and the kit is assembled in the USA.
