Description
The Mishimoto Intercooler Pipe and Boot Kit (MMICP-DMAX-11KBK) is a direct bolt-on forced induction upgrade engineered for the 2011-2016 6.6L Duramax LML, replacing the factory piping’s restrictive bends with larger, mandrel-bent aluminum tubing finished in polish. The kit pairs the pipes with Mishimoto’s silicone boots featuring DuraCore technology, a synthetic inner-layer material built to handle the heat, pressure, fuel, and oil exposure that comes with a hard-working diesel induction system. Designed to complement the Mishimoto 6.6L Duramax Performance Intercooler, this kit is a complete forced induction system solution for the LML platform.
Factory intercooler piping on the 2011+ Duramax relies on numerous restrictive bends and small-diameter tubing that chokes airflow before it reaches the engine. Mishimoto’s larger pipes open up that path for a significant increase in airflow, resulting in more power and lower EGTs, and the kit requires no additional tuning to install. Backing every connection are Mishimoto’s constant-tension T-bolt clamps, which provide accurate, consistent holding power on the DuraCore silicone boots to help prevent leaks and blowouts over time. For owners looking to upgrade their forced induction system with real-world airflow gains and long-term reliability, this Mishimoto kit delivers a straightforward, bolt-on answer.
