The S&B Cold Air Intake for the 2011-2016 Chevy / GMC Duramax 6.6L was engineered to minimize air restriction and flows 29.10% better than stock. This kit comes with a fully enclosed airbox that protects the filter from dirt and keeps out engine heat.
Stronger, Better Silicone Parts.
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.
Cooler Air. Better Performance
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.
