The Best Intake Performance

The solution to intake performance is to bring or “ram” cool outside air into the factory intake system. As the originators of the “Ram Air Scoop”, RPi had lead the way in designing Ram Induction systems for several applications. All induction kits are tested in house under strict conditions. RPi Ram Air kits are NEVER tested with the hood open and dyno sessions NEVER allow for “cool down” periods. This ensures that RPi customers get the best in their intake performance.

RPi’s Ram Air Induction converts your factory intake system into a ram air type. Other aftermarket induction kits mostly suck in hot air causing a loss of performance. The use of heat shields is not very affective as heat shields mainly work to block radiant heat. Utilizing the stock intake boxes, expect a 5-11whp gain with 70mph airflow. RPi’s Ram Air come with a 30-day money back guarantee.
