Description
The Mishimoto MMICP-DMAX-11HBK is a direct bolt-on hot-side intercooler pipe and boot kit engineered to replace the factory forced induction plumbing on the Duramax-powered trucks it fits. Where the factory hot-side pipe runs a restrictive 2.5in path full of chokepoint bends, Mishimoto opens things up with a 3in diameter mandrel-bent aluminum pipe, delivering a genuine step up in airflow through the forced induction system without requiring additional tuning.
This forced induction upgrade is built as a two-piece design that mirrors the factory pipe layout, making installation more straightforward while still delivering a meaningful gain in flow, power potential, and lower EGTs. Every kit includes Mishimoto’s silicone boots built with DuraCore technology, a synthetic inner-layer material engineered for superior resistance to heat, pressure, fuel, and oil compared to standard silicone, helping prevent leaks and blowouts and extending the service life of the induction system. Mishimoto backs the connection with constant-tension T-bolt clamps for accurate, consistent holding power, and the polished aluminum finish gives the induction piping a clean, finished look under the hood. This hot-side pipe kit is designed to pair with the Mishimoto 6.6L Duramax Performance Intercooler for a complete forced induction upgrade.
