Premium Intercooler Kit for GM 6.6L Duramax

If your 2002–2004 Duramax is working harder than ever—whether towing heavy loads or making big power on the street—you know how important it is to keep intake temps under control. That’s where the Mishimoto Silver Intercooler Kit comes in. This isn’t just an upgraded intercooler—it’s a complete airflow system built to handle heat, boost, and horsepower in one clean, performance-driven package. At the heart of this kit is Mishimoto’s performance intercooler, featuring a high-capacity bar-and-plate core with cast aluminum end tanks. This setup delivers a significant drop in intake temps and reduced exhaust gas temperatures (EGTs), which helps prevent power loss and keeps your engine safer under load. Whether you’re pulling a fifth wheel or pushing the limits on a tune, this intercooler is built to perform.

High-Quality Pipes and Hardware

The kit also includes mandrel-bent aluminum intercooler piping, designed to remove restrictions and smooth out airflow for better throttle response and turbo efficiency. The pipes are polished for a sleek, show-quality finish, and they’re a perfect match for the silver intercooler core. To ensure a leak-free, long-lasting connection, Mishimoto adds their DuraCore silicone boots and constant-tension T-bolt clamps. The DuraCore material stands up to extreme heat, pressure, fuel, and oil exposure far better than standard silicone, helping you avoid the dreaded boot blowout. This complete setup is engineered for durability and performance, with everything you need for a clean, reliable install. And like all Mishimoto products, it's backed by their signature lifetime warranty.
