The Flow Control System utilizes a newly designed base in combination with a unique lid designed to reduce intake turbulence. The resulting smooth, laminar flow enhances cylinder filling, horsepower, and torque. The filter element is the world famous K&N Filtercharger® for the ultimate in airflow and filtration.
The flow control system is legal in California only for racing vehicles which may never be used, registered, or licensed for use upon a highway. See knfilters.com for CARB status on each part for a specific vehicle.
