50-335 Ness, Stage 1 Big Sucker air cleaner. Smooth black

The Arlen Ness Stage 1 Big Sucker is a legendary upgrade for a reason, and this version comes with a sleek black anodized smooth billet aluminum cover. Designed for electronic throttle models, it features the patented hidden breather backing plate. This clever design uses O-rings at the heads and exits inside the throttle body, creating a virtually closed-loop system that eliminates the need for messy external hoses. The kit includes a pre-oiled black cotton gauze filter and a one-piece aluminum backing plate with a radiused inlet for unobstructed airflow. It fits 2016 to 2017 Softail models, the 2017 Dyna Low Rider S, and 2008 to 2016 Touring and Trike models. It is a proven way to increase horsepower and torque while cleaning up the side of your motor.
