Product Highlights:

Our cold air intake for the 2020-21 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 2020-21 3.0L Duramax intake kit can be installed by connecting directly to the stock intake tube. For even better performance, S&B includes an additional intake tube to connect directly to the turbo to maximize airflow.

Our new snap-In lid design requires no screws to secure it to the box. This makes installation and inspection quick and easy. Our silicone edge trim ensures an airtight seal, protecting against unwanted, power-robbing engine heat.

The air filter, coupler, lid seal and box plug are all made with silicone. Silicone is a premium rubber which will seal better and last longer. It handles temperatures as high as 400F without cracking or tearing and won’t deteriorate over time.

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.

S&B devotes a huge amount of resources to engineer our intakes that allow your engine to run properly with stock calibration or enhanced tuning. An injection molded MAF plate in conjunction with a foam MAF sensor gasket ensures a true OE seal to the sensor.
