EGR Delete Kit FOR 2017-2019. 2020-2023 WILL REQUIRE SMALL MODIFICATIONS ON THE EGR DELETE KIT.

Factory cooler setups recirculate soot and harmful gasses through your engine causing build-up and clogs, resulting in loss of performance and proven mechanical issues. Cooler Upgrade Kits remove those concerns from the equation. Components install with an exact fit resulting in a longer lasting & better running truck, less turbo lag for better throttle response, cooler engine temps, less weight and a cleaner looking engine bay. Proudly Made in Canada.
