A revolution in air cleaner technology! The Flow Control System utilizes a specially contoured base in combination with a unique lid, featuring a tongue or protrusion that reduces intake turbulance. The resulting smooth, laminar flow enhances cylinder filling with a typical 15+ HP increase on a 350 cubic inch engine.

Includes the reusable K&N Filtercharger filter element for maximum airflow, filtration, and serviceability. Will not fit Holley Pro Series (Dominator).

Available for carbs with or without choke air horn. "With choke" means the choke horn is still on the carb. "Without choke" means the choke horn has been removed.
