The S&B Intake System for the '13-'18 Cummins takes the principles and design of the factory Ram Active Air and improves upon the entire system by combining the benefits of the Active Air with the size and available air volume that S&B is known for. 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.
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, this 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. Dam MUST be used in harsh weather conditions including but not limited to rain, sleet, or snow as engine damage can occur. SB is not responsible for engine damage due to failure to use the dam as instructed.
Cleanable or dry filters. You pick. This kit is offered with two types of filters: cotton (cleanable) or dry (disposable). Since you don't sacrifice performance with either choice, the decision comes down to your preference to throw away the filter or clean it. Part numbers for dry filter intakes end with 'D'.
