GAS 6.6L Engine Only, Not Diesel

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. The snap-in lid 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. Our intake features two air inlet points. A large opening at the fender and a large scoop opening at the bottom. If you want to customize the amount of air you take in, we provide an optional box plug that can seal off the bottom scoop 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.
