The Mishimoto Hot-Side Intercooler Pipe & Boot Kit increases reliability, performance and looks under the hood of your 2011-2016 GM 6.6L Duramax LML. The factory hot-side pipe on your truck features numerous restrictive bends that choke the engine with 2.5" piping. The 3" diameter of the Mishimoto intercooler pipes provides a significant increase in airflow that results in more power and lower EGTs. The Mishimoto hot-side intercooler pipe and boot kit is a direct bolt-on upgrade and features mandrel-bent aluminum with a polished finish. For ease of install, Mishimoto designed this kit as a two-piece design, similar to the factory pipe.

Mishimoto intercooler piping kits feature our Silicone Boots with DuraCore technology. 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. To add even more reliability this kit includes Mishimoto Constant-Tension T-Bolt Clamps for accurate and consistent holding power. This hot-side pipe is the perfect addition to the Mishimoto 6.6L Duramax Performance Intercooler. The Mishimoto hot-side intercooler pipe and boot kit is made in the USA and includes our signature Mishimoto Lifetime Warranty.
