Product Details

If you're looking to keep your 2011-2016 Chevrolet Silverado 2500 HD or GMC Sierra 2500 HD's 6.6L Duramax engine running cool and strong, especially under load or with performance upgrades, this Mishimoto intercooler kit is a solid solution. High exhaust gas temperatures (EGTs) and a stock intercooler that's struggling to keep up can limit your truck's potential and put stress on the engine. This kit is designed to address those issues head-on by significantly improving airflow and reducing intake air temperatures.

The heart of this kit is a substantially larger intercooler featuring a bar-and-plate core with cast aluminum end tanks. It boasts a 101% increase in core volume and is 73% thicker than the factory unit, allowing it to absorb and dissipate more heat. Complementing the intercooler are mandrel-bent aluminum pipes, polished to a clean finish, which are shaped to eliminate restrictive bends and allow for smoother, unimpeded airflow. These pipes connect using Mishimoto's silicone boots, which incorporate DuraCore technology. This advanced synthetic material is built to resist heat, pressure, fuel, and oil, offering superior durability and preventing leaks or blowouts compared to standard silicone. Constant-tension T-bolt clamps ensure a secure and consistent connection throughout the system.

This comprehensive kit includes everything needed to replace your stock intercooler and piping. The improved cooling and airflow can lead to lower EGTs, better boost pressure tolerance, and overall more consistent performance from your Duramax engine. Mishimoto backs this kit with their signature Lifetime Warranty, giving you confidence in its long-term reliability.
