Description
The Mishimoto MMINT-DMAX-11SL is a Sleek Silver, direct-fit forced induction intercooler engineered specifically for the 2011-2016 Chevrolet and GMC 6.6L Duramax LML. Built around a bar-and-plate core with cast aluminum end tanks, it replaces the factory unit with a dramatically larger core designed to move more air and shed more heat under load. This isn’t a universal induction system bolt-on afterthought — it’s a Duramax-specific piece from Mishimoto’s forced induction lineup, built to protect the engine investment underneath the hood.
High intake and exhaust gas temperatures can rob a diesel of performance and, over time, put real stress on internal components. As a performance induction upgrade, this intercooler delivers a 101-percent increase in core volume and a core that’s 73-percent thicker than the factory piece, giving the induction engine more surface area to cool compressed air before it reaches the cylinders. Inside the hot-side end tank, an air diverter reduces turbulence and spreads airflow evenly across the core, which in turn helps reduce turbo stress and extend turbo life. Whether the truck is running stock power or has been built up, this forced induction core is designed to support substantial boost pressure while keeping intake air temperatures and EGTs in check.
