Description
The Mishimoto MMINT-DMAX-17KBKBK is a purpose-built performance intercooler kit engineered specifically for the 2017-2019 Chevrolet and GMC 6.6L Duramax L5P. Built around a massive 68mm-thick bar-and-plate core with cast-aluminum end tanks, this forced induction upgrade replaces the factory intercooler system with a unit designed to handle higher heat and boost without cracking. Paired with 3.0in mandrel-bent aluminum piping, it’s a complete solution for anyone who has felt the limits of the stock L5P induction system.
Mishimoto engineered this intercooler and piping kit to reduce restriction throughout the entire forced induction pathway. The core itself is 70-percent thicker than the factory intercooler, and combined with larger inlets and outlets on the cast end tanks, overall system restriction is reduced by up to 64-percent compared to stock. The included hot-side and cold-side piping eliminates the factory restrictive resonator, improving flow by up to 55-percent, while Mishimoto’s DuraCore silicone boots and constant-tension T-bolt clamps keep every connection secure under boost. A CNC-machined quick-disconnect fitting with new O-ring and spring clip, bead-rolled pipe ends, and factory sensor/harness mounting points mean this induction system upgrade installs like it came from the factory, not like a universal forced induction kit.
Vehicle Applications
This kit is a direct, specific fit for the 2017-2019 Chevrolet Silverado 2500 HD and 3500 HD (WT, LT, LTZ, and High Country trims) as well as the 2017-2019 GMC Sierra 2500 HD and 3500 HD (Base, SLE, SLT, and Denali trims), all equipped with the 6.6L Duramax L5P diesel engine on the GMT K2 chassis. No other years, makes, or models are supported by this kit.
