Fed up with high EGTs and an intercooler setup that isn't keeping up with the demands of your Duramax? The solution is finally here! Mishimoto is proud to expand their line of Duramax performance parts to include the 2011-2016 Chevrolet/GMC 6.6L Duramax LML Intercooler Kit! This Duramax performance parts kit includes everything you need to improve airflow, substantially decrease air-charge temperatures, and support your truck at any power level. The Mishimoto Duramax intercooler piping kit is the first key component; our engineers have maximized airflow by eliminating restrictive bends, allowing for a smooth and unimpeded airflow. The piping is constructed with mandrel-bent aluminium polished to a flawless finish.

This Duramax intercooler kit includes Mishimoto silicone boots with DuraCore™ technology and Constant-Tension T-Bolt Clamps for accurate and consistent holding power. Mishimoto DuraCore™ technology is the synthetic material that comprises the innermost layer of all Mishimoto silicone diesel boots. Compared to normal silicone, DuraCore™ provides superior resistance to heat, pressure, fuel, and oil. This effectively increases the life of our boots by preventing leaks and blowouts.

This package is rounded out with the Mishimoto Duramax 6.6L intercooler which features cast aluminium end tanks and a bar-and-plate core, all designed to provide cool, dense air to your engine. The Mishimoto Duramax intercooler features a 101% increase in core volume and is 73% thicker compared to the factory cooler, allowing for cooler intake temperatures, lower EGTs, and increased boost pressure tolerance.

All the components in this kit are engineered to last, just like your truck. Offered with either a Sleek Silver or Stealth Black intercooler, the Mishimoto 6.6L Duramax LML Intercooler Kit, like all of our Duramax performance parts, is protected by our signature Mishimoto Lifetime Warranty.
