Product Overview

MAXIMUM PERFORMANCE

This cold air intake for the 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.

SNAP-IN LID DESIGN

The innovative snap-In lid design makes installing and inspecting quick and easy. Our silicone edge trim provides a protective seal against unwanted, power-robbing engine heat and debris. This kit comes with a massive, highly-efficient air filter which results in better performance and protects your engine. Available in either 8-layer Cotton Cleanable or Dry Extendable media.

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.
