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.
