S&B Cold Air Intake 2003-2007 Cummins 5.9L
We took something good and made it even better.
Uses the same motor that drives Ram Active Air 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.
Monitor your ram air.
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.
Want more air ? Use both inlets.
Unlike stock which uses only one inlet at a time, our kit gives you the option of massive dual inlet airflow. Simply remove the dam from the gate arm and re-attach when desired or to protect against inclement weather.
Note: The gate arm remains active even with the dam removed. This will prevent you from getting an Active Air Box code when both inlets are open.
Innovative filter inlet. Bigger is better.
The full round inlet radius provides for a smooth transition while allowing for a larger filter with more surface area. The result is better airflow and filtration.
