Uses the same motor that drives Ram Active AirTM to activate its swing gate, giving you all the benefits of the stock system, plus much more. Draws air from the wheel well inlet under normal driving conditions or inclement weather conditions (ice, snow, rain) to protect against the elements.
In extreme heat, high loads, or high altitudes the swing gate pivots when your truck accelerates to full throttle, opening the ram-air duct mounted behind the front grille and exposing cooler and less restrictive air to your engine.
Our active monitoring light alerts you when the ram-air gate is open.
Testing shows that the ram-air inlet opens when outside temperatures are greater than 91?F and the truck is at full throttle. The ram-air inlet stays open for approximately 3-5 miles or until the truck slows to close to 5 mph. This process repeats itself. Ram-air activity varies with your driving conditions.
Unlike stock which uses only one inlet at a time, our kit gives you the option of massive dual 
inlet airflow.
