50-290 Ness, Stage 1 Big Sucker air cleaner kit. 10-Gauge B.

Boost your engine's performance with the Arlen Ness Stage 1 Big Sucker air cleaner kit. This version features a 10-Gauge black anodized billet aluminum cover and a matching black backing plate for a dark, custom look. The patented hidden breather system is a game changer, eliminating external hoses by routing gasses through O-rings at the heads directly into the throttle body. The kit includes a pre-oiled black cotton gauze filter and a radius air inlet to ensure maximum, unobstructed airflow for increased horsepower and torque. Designed for electronic throttle bikes, it fits 2016 to 2017 Softails, the 2017 FXDLS, and 2008 to 2016 Touring and Trike models. It is a proven, one-piece aluminum design that delivers both style and serious breathing room for your Harley.
