S&B Duramax Air Intake

Our cold air intake for the Chevy / GMC Duramax 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.

Silicone is a premium rubber which will seal better and last longer. It handles as much as 400F without cracking or tearing. With a high friction surface and no oily residue, our silicone filters and couplers won’t slide off the tube. Available in either 8-layer Cotton Cleanable or Dry Extendable media.

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.

Our one piece air box design features an integrated box seal that keeps out unwanted engine heat. The cooler the air, the greater the density, resulting in better performance.
