Description
A properly designed intake system directly impacts carburetor efficiency and engine reliability—especially on high-performance Twin Cam applications where every airflow optimization matters. The Arlen Ness Big Sucker eliminates restrictive breather plumbing and filter housings that create parasitic losses, while its patented hidden breather technology maintains a sealed system that keeps contaminants out and performance up. This is a bolt-on upgrade that simplifies your intake setup without sacrificing functionality or aesthetics.
