Choose your airflow
Our 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
With a properly mapped Mass Air Sensor, this kit was designed to avoid check engine lights. This is where we run away from the competition as vehicles are becoming more complex. We devote a huge amount of resources to engineer intakes that will allow your engine to run properly with the stock calibration or with enhanced tuning.

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.

Stronger, better silicone parts
Silicone is a premium rubber that can withstand temperatures up to 400?F and won’t crack or tear with age. It’s tough yet elastic enough to stretch, then snap into a perfect seal. That’s why we used silicone to build this kit’s filter, inlet, coupler, and tube sleeve.
