Improve the power and efficiency of your 2006-2010 GM 6.6L Duramax with the Mishimoto cold-side intercooler pipe and boot kit. The factory cold-side pipe for the 2006-2010 Duramax features numerous restrictive bends that greatly decrease flow. The 3.5” diameter of the Mishimoto intercooler pipe provides a significant increase in airflow that results in more power and lower EGTs. The Mishimoto cold-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 cold-side pipe is the perfect addition to the Mishimoto 6.6L Duramax performance intercooler. The Mishimoto cold-side intercooler pipe and boot kit is made in the USA and includes our signature lifetime warranty.
