S&B Filters 3.0 Duramax Cold Air Intake | 75-5137-1 | 2020+ GM Duramax 1500 3.0L

Our cold air intake for the 2020+ Chevy Silverado / GMC Sierra 3.0L Duramax was engineered to minimize air restriction and flow better than stock. This kit comes with a fully enclosed airbox that protects the filter from dirt and keeps out engine heat.

The 75-5137 intake kit has (3) airflow configurations. Its Unique Airbox design provides more air to the filter by using a scoop that captures cool air from the front quarter panel. S&B also includes a silicone box plug that can be installed or removed depending on personal preference and airflow requirements. 

Silicone Box Plug removed: This configuration will provide an extra air inlet that will be pulled from the driver side fender area. 

Silicone Box Plug installed: This configuration will seal the secondary air inlet located on the side of the box facing the vehicle fender. The front-facing grill inlet and the front scoop will become the main source of airflow into the Intake Box.
