Description
The Mishimoto MMICP-DMAX-11CBK is a cold-side intercooler pipe and boot kit engineered specifically to replace the failure-prone plastic factory pipe and boot found on 6.6L Duramax LML trucks. Built from polished, mandrel-bent aluminum, this kit is designed to stand up to the heat and pressure that the stock plastic components simply were not built to handle.
As a forced induction upgrade, this pipe kit reworks the cold side of the intercooler piping with 3.5-inch mandrel-bent aluminum tubing that eliminates the restrictive bends found in the factory forced induction system. By smoothing out airflow through the induction system, the kit is designed to deliver an improvement in airflow, power, and EGTs without requiring any additional tuning. For anyone researching a durable forced induction pipe upgrade or a stronger induction system for their Duramax, this kit replaces the weak link in the factory piping with a setup built for sustained boost and heat cycling.
