Description
The Mishimoto MMINT-DMAX-11KBK is a purpose-built forced induction intercooler kit engineered specifically for the 2011-2016 Chevrolet and GMC 6.6L Duramax LML. Tired of high EGTs and a factory intercooler system that can’t keep pace, Mishimoto answered with a bar-and-plate core that delivers a 101-percent increase in core volume and a core that is 73-percent thicker than the factory unit, backed by a Mishimoto Lifetime Warranty.
This forced induction upgrade replaces the restrictive factory induction system with mandrel-bent, polished aluminum piping — 3.5-inch on the cold side and 3.0-inch on the hot side — that eliminates tight factory bends and adds 42-percent more internal volume than the stock intercooler piping. An air diverter built into the hot-side end tank reduces turbulence and evenly distributes airflow across the core, so the induction engine feeding your Duramax runs cooler and more consistently at any power level. Because the kit is a direct, specific-fit performance replacement, it installs without requiring additional tuning, while lower air-charge temperatures and improved airflow help reduce turbo stress and extend turbo life.
Vehicle Applications
This Mishimoto intercooler kit is a direct fit for 2011-2016 Chevrolet Silverado 2500 HD and 3500 HD, including WT, LT, and LTZ trims across all those years, plus High Country trims for 2015-2016. It is equally suited to 2011-2016 GMC Sierra 2500 HD and 3500 HD SLE, SLT, and Denali trims, GMC Sierra WT trims for 2011-2014, and GMC Sierra Base trims for 2015-2016 — all equipped with the 6.6L Duramax LML engine.
