Engineered To Maximize Flow And Minimize Heat Soak

The Mishimoto MMINT-DMAX-11KBK Black Intercooler Kit is a complete cooling solution for 2011–2016 GM 6.6L Duramax LML trucks. At the core of this system is a bar-and-plate intercooler featuring cast aluminum end tanks, offering improved durability and heat dissipation compared to the factory unit. With a 101 percent increase in core volume and a 73 percent thicker design than stock, it effectively reduces intake air temperatures and helps lower exhaust gas temperatures under load. The included mandrel-bent aluminum piping eliminates airflow restrictions found in the factory setup, ensuring smoother and more efficient boost delivery. DuraCore silicone boots resist oil, fuel, and high temperatures better than standard silicone, while constant-tension T-bolt clamps maintain a tight seal even during temperature changes and boost spikes. This kit is compatible with both stock and modified trucks, giving you the flexibility to support higher power levels with confidence. Designed to perform and built to last, this system ensures your Duramax stays cool, even under extreme conditions.
