RPi's Ram Air Scoops 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 heatshields are not very affective as heat shields mainly work to block radiant heat.
Utilizing the stock intake boxes, expect an 5-8whp gain with 70mph airflow.
