The GMC Sierra 3500 Intercooler Kit by Mishimoto for the 6.6L Duramax, available in sleek black, is designed for the 2002-2004 models. This comprehensive kit provides the ultimate solution for high EGTs and a lackluster intercooler setup that can’t keep up with your Duramax’s demands.

This intercooler kit is meticulously engineered to improve airflow and significantly reduce air-charge temperatures, boosting your vehicle’s efficiency and performance. The cornerstone of the kit is the mandrel-bent aluminum piping, crafted to eliminate restrictive bends and ensure unimpeded airflow. The Mishimoto silicone boots, enhanced with DuraCore technology, offer superior resistance to heat, pressure, fuel, and oil, effectively extending the life of the components by preventing leaks and blowouts. The kit is completed with a durable intercooler featuring cast aluminum end tanks and a bar-and-plate core, providing greater volume than factory coolers, leading to reduced air-charge temperatures and improved EGTs.
