The Mishimoto MMICP-DMAX-11CBK Cold-Side Intercooler Pipe & Boot Kit for your 2011-2016 GM 6.6L Duramax is an upgrade that increases looks, performance and reliability on your Duramax Pickup. 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.

This kit includes Mishimoto 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. The cold-side pipe and boot kit is the perfect addition to the Mishimoto 6.6L Duramax Performance Intercooler. This kit is made in the USA and includes our signature Mishimoto Lifetime Warranty.
