2020-2024 Duramax S&B Cold Air Intake Kit (75-5137-1)

Fits

Minimize air restriction and flow better than stock;  a fully enclosed airbox that protects the filter from dirt and keeps out engine heat. S&B's snap-In lid design requires no screws to secure it to the box. The silicone edge trim provides a protective seal against unwanted, power-robbing engine heat and debris. 

The 75-5137-1 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.
