Description
The Mishimoto MMINT-DMAX-17KSLBK is a purpose-built forced induction upgrade engineered specifically for the 2017-2019 Chevrolet and GMC 6.6L Duramax L5P. At the heart of this kit sits a massive 68mm-thick bar-and-plate intercooler core with cast-aluminum end tanks, paired with 3.0-inch mandrel-bent aluminum piping designed to move more air with far less restriction than the factory forced induction system.
Mishimoto engineered this performance induction kit to address the known limitations of the factory L5P intercooler system. The 68mm bar-and-plate core is 70-percent thicker than stock, and combined with larger end-tank inlets and outlets, the complete induction system reduces restriction by up to 64-percent compared to the factory unit. The 3.0-inch mandrel-bent hot-side and cold-side piping eliminates the restrictive factory resonator, improving flow by up to 55-percent over the stock forced induction turbo piping, while Mishimoto silicone boots with DuraCore technology and constant-tension T-bolt clamps keep every connection secure under boost.
Vehicle Applications
This kit is a direct, specific fit for 2017-2019 Chevrolet Silverado 2500 HD and 3500 HD (WT, LT, LTZ, and High Country trims) and 2017-2019 GMC Sierra 2500 HD and 3500 HD (Base, SLE, SLT, and Denali trims) equipped with the 6.6L Duramax L5P engine, chassis code GMT K2. Whether your truck is bone stock or heavily modified, this induction system upgrade bolts in place of the factory intercooler and piping.
