With the front inlet sealed, our intake will only draw air from the wheel well inlet in normal driving or inclement weather conditions to protect against the elements (ice, snow, rain).
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.
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. Dam MUST be used in harsh weather conditions including but not limited to rain, sleet, or snow as engine damage can occur. S&B is not responsible for engine damage due to failure to use the dam as instructed.
Silicone is a premium rubber which will seal better and last longer. It handles as much as 400° F 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
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.Patent Pending
