DHD 291-108 LML Duramax 3" High Flow Upper Intake Upgrade Kit

(Throttle Valve & Grid Heater Delete)

Brand new for DHD is our high flow intake manifold upgrade kit for the new body style LML Duramax pickups. This kit will bolt right to the factory y-bridge and includes all necessary hardware for installation. This kit will completely remove your factory grid heater and throttle valve in order to offer the maximum amount of unrestricted air flow throughout your intake system. You can completely remove the EGR system with this kit, as it will come with all the hardware that you need to do the job. You could also opt to leave the system intact, and not use the hardware if you aren’t looking to have to change the up-pipe.  

Item is sold in raw aluminum. Custom powder coating is available per request. Item in this picture is powder coated.

Note: If the EGR Cooler is not removed, you will need an EGR Test Plate. If you are removing the EGR assembly, you will need a modified up-pipe or LB7 up-pipe. Also, if you don’t have one, you WILL need a DHD # 101-287 LML Duramax Turbo Resonator Delete Plate in order to install this kit.
