Description
The Mishimoto MMINT-DMAX-17BK is a direct-fit performance intercooler engineered specifically for the 2017-2019 Chevrolet and GMC 6.6L Duramax L5P. It centers on a 68mm-thick bar-and-plate core that’s 70-percent thicker than the factory unit while cutting flow restriction by more than 64 percent compared to the stock intercooler.
High intake air temperatures can quietly rob a forced induction engine of performance, so this Mishimoto forced induction intercooler is built to keep your Duramax’s induction system running cooler and more consistently under load. Robust cast-aluminum end tanks are engineered to resist cracking under the high heat and boost pressures that come with forced induction, while an enlarged inlet and outlet were sized up to improve flow through the entire induction system. The result is a performance intercooler designed to support your 6.6L Duramax L5P’s induction system whether you’re towing, hauling, or simply want cooler, more reliable charge-air temperatures.

This intercooler is a specific fit for the 2017-2019 Chevrolet Silverado 2500 HD and 3500 HD, available across High Country, LT, LTZ, and WT trims, as well as the 2017-2019 GMC Sierra 2500 HD and 3500 HD in Base, Denali, SLE, and SLT trims.
