Engineered For Lower Temps And Higher Performance Gains

The Mishimoto MMINT-DMAX-11KSL Intercooler Kit offers a serious upgrade in thermal efficiency and airflow for the 2011–2016 Duramax LML platform. At the heart of this system is a bar-and-plate intercooler with cast aluminum end tanks, delivering exceptional strength and heat dissipation in high-boost conditions. The intercooler core itself is 73 percent thicker than the factory unit and offers a 101 percent increase in volume, which significantly reduces intake air temperatures under load. Paired with polished, mandrel-bent aluminum piping, the system minimizes turbulence by eliminating the restrictive bends found in stock piping. The included DuraCore silicone boots feature a reinforced internal lining designed to withstand exposure to oil, fuel, heat, and pressure without breaking down or ballooning. Constant-tension T-bolt clamps maintain consistent pressure across varying temperatures, helping prevent boost leaks and hose blowouts. This intercooler kit supports both stock and modified trucks, making it ideal for anyone looking to improve cooling efficiency, extend engine life, and maintain consistent power output under demanding conditions.
