In extreme heat, high loads, or high altitudes S&B’s swing gate pivots when your truck accelerates to full throttle, opening the ram-air duct mounted behind the grille which releases cooler and less restrictive air to your engine. Our intake uses the same motor that drives Ram-Air to activate our 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 to protect against the elements.
Silicone Filters and Couplers
Silicone is a premium rubber which will seal better and last longer. It handles as much as 400F without cracking or tearing. With a high friction surface and no oily residue, our silicone filters and couplers won’t slide off the tube or require you to wash your hands.
Customize Your Airflow
Our swing gate functions the same as the stock air box, only better. 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 harsh 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.
