50-577 Ness, Stage 2 Big Sucker air cleaner kit

This Arlen Ness Stage 2 Big Sucker kit provides maximum airflow for Evolution Big Twins with a clean, blacked-out aesthetic. The kit includes a black anodized one-piece billet aluminum backing plate and a high-performance filter that offers 20% more surface area than standard Stage 1 kits. By using Ness's patented hidden breather technology, this kit eliminates the need for external hoses and hardware, routing breathers directly into the mouth of the carburetor. It is sold without an outer cover, so you can choose a Ness Stage 2 cover or a custom 8-inch round cover to finish the look. This kit is a direct fit for 1993 to 1999 Evolution Big Twin models equipped with a CV carburetor.
