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. After watching all the work to create the Flow Control, it seems that it is compromised by a badly designed wrap. K&N thought it just seemed smart to control that part of the installation also. The deflector shield is designed to control heat and help the air flow.
