Our 2017-2018 Duramax intake has two airflow configurations dependent on your airflow requirements. With the optional box plug removed, you'll get over 43% more airflow than the stock intake.
The hood scoop inlet holds the clear lid with no hardware required. It snaps easily into place for a snug, perfect fit.
This Duramax intake includes a massive air filter made of a high efficiency, low restriction media as well as a silicone base and top for added protection against engine heat.
In conjuction with a foam MAF gasket, the injection molded MAF plate ensures a quality seal around the MAF sensor that prevents any air leaks.
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 in building this kit's filter, hood scoop, coupler, and tube seal.
With our full color, step by step instructions, you'll be breathing easy in 45 minutes or less with just basic tools.
