Maximum Performance

Our cold air intake for the 2020 Silverado / Sierra Duramax L5P 6.6L 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.


New Snap In Lid Design

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.


Premium Silicone Components

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


Choose Your Airflow

More air equals better performance. The Duramax L5P 6.6L intake features three air inlet points. If you want to customize the amount of air you take in, we provide an optional box plug that can seal off one inlet point.

When to use the Box Plug?
Stock intake boxes are a significant contributor to poor airflow which is why S&B designs custom air boxes with secondary and/or enlarged openings. With that said, S&B recognizes the benefits of cooler air, so we have included a plug to seal off the opening if desired. For optimal performance, we recommend that the intake be used without the box plug, except in conditions of an extreme heatwave.


No Check Engine Lights

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. This kit was designed to avoid check engine lights with it's properly mapped Mass Air Flow Sensor.

Silicone Hood Scoop Seal

The L5P intake kit features a silicone air scoop seal that integrates with the OEM hood scoop and feeds air to the filter. More airflow equals better performance.
