2011-2016 Duramax S&B Cold Air Intake Kit
The S&B Cold Air Intake for the 2011-2016 Chevy/GMC Duramax 6.6L was engineered to minimize air restriction and flows better than 29.10% better than stock.
This kit comes with an enclosed airbox that protects the air filter from dirt, debris and keeps engine heat out.
The 2011-2016 Duramax intake was designed with a secondary inlet, resulting in even better airflow.
A silicone plug is included for those who prefer to pull in air only from the fender inlet.
S&B’s one piece air box design features an integrated box seal that keeps out unwanted engine heat.
The cooler the air, the greater density, resulting in better performance.
