Improve the power and efficiency of your Duramax with the Mishimoto hot-side intercooler pipe and boot kit. The factory hot-side pipe for the 2004.5-2010 Duramax features numerous restrictive bends and chokes the engine with 2.5 piping. The 3 diameter of the Mishimoto intercooler pipe 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. 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 lifetime warranty.
