S&B's cold air intake for the 2011-2016 Chevy / GMC LML 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, their silicone filters and couplers won’t slide off the tube. Available in either 8-layer Cotton Cleanable or Dry Extendable media.
CHOOSE YOUR AIRFLOW
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.
AVOID CHECK ENGINE LIGHTS
S&B devotes a huge amount of resources to engineer intakes that allow your engine to run properly with stock calibration or enhanced tuning. This kit was designed to avoid check engine lights with its properly mapped Mass Air Flow Sensor.
COOLER AIR. BETTER PERFORMANCE
The 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.
