Mishimoto Intercooler Cold Side Pipe/Boot Kit for Chevrolet/GMC 6.6L Duramax 11+

More Views


Mishimoto has developed a cold-side intercooler pipe and boot kit for the 2011+ 6.6L Duramax. The plastic factory pipes and boots do not stand a chance against the heat and pressure of your high-powered Duramax;. Upgrade today to the Mishimoto kit for increased reliability, durability, and performance. The Mishimoto cold-side pipes are constructed of 3.5 mandrel-bent aluminum with a polished finish. This pipe kit features a two-piece design for easy installation and removal, as well as a CNC-machined AIT sensor bung allowing you to retain your factory AIT sensor. The cold-side pipe eliminates restrictive bends in the factory pipe, allowing for improvements in airflow, power, and EGTs.
