50-575 Ness, Stage 2 Big Sucker air cleaner kit. No cover

The Arlen Ness Stage 2 Big Sucker kit is engineered for high-output engines that require maximum breathing capability. This version features a black anodized one-piece billet aluminum backing plate and a high-performance filter with a zinc-plated housing, providing 20% more filtration area than Stage 1 kits. The patented hidden breather technology routes gasses through the plate to the throttle body, eliminating external hoses. This kit is supplied without a cover, making it perfect for use with Ness Stage 2 covers or custom 8-inch round covers with a central mount. It fits 2016 to 2017 Softails, the 2016 to 2017 FXDLS, and 2008 to 2016 Touring and Trike models with electronic throttle. It is a proven way to gain more horsepower and torque.
