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.
