Big Sucker Stage I Air Filter – ARLEN NESS (Ref. 50-571)
Designed for vintage/classic style enthusiasts and long road trips, the Big Sucker Stage I by Arlen Ness combines a sleek look with robust construction. Its one-piece aluminium support plate incorporates hidden breather technology: each breather is equipped with O-rings at the cylinder heads and connects directly to the injector/carb inlet, ensuring clean engine ventilation without the need for external hoses.
The large intake opening radius minimises obstructions for smooth airflow and optimised engine breathing. Subtle black aesthetics that fit perfectly on customs and Dyna models while maintaining a classic silhouette.
