    More Airflow. Better Performance

    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.

    Full Silicone Hood Scoop

    The hood scoop inlet holds the clear lid with no hardware required. It snaps easily into place for a snug, perfect fit.

    Massive Air Filter

    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.

    Injection Molded MAF Plate

    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.

    Premium 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 in building this kit's filter, hood scoop, coupler, and tube seal.
