The Performance Auto category was created to incorporate the Domestic and Muscle Car Type into one strong field. With extensive Research & Development, the Power-Flow series was released to the highly anticipated Performance Auto Market. Features that make the Power-Flow series stand out can be seen in the use of Cast Aluminum Components as opposed to the traditional Aluminum/Rotor Mold Type Intake Systems. The necessity of the Cast Aluminum Components is due to maximizing air volume and for fitment reasons. Aesthetically appealing, this unique design allowed us to optimize every aspect of airflow. Our Performance Auto kits will be comprised of a full Cast Aluminum Piece or as a combination of both- Cast & Aerospace Tubing and include the patent pending MR Technology Process and may use the Injen Power Box.
