Construction & Design:

The Mishimoto Intercooler Kit is built with durability and performance in mind. The intercooler core utilizes a bar-and-plate design, which is known for superior heat transfer and structural integrity compared to tube-and-fin alternatives. Cast aluminum end tanks provide ruggedness and resistance to cracking under high boost pressures. The intercooler piping is crafted from mandrel-bent aluminum tubing, ensuring smooth bends that minimize airflow restrictions and turbulence.

Mishimoto’s proprietary DuraCore silicone boots form the critical connection points in the system. These boots feature a synthetic inner layer that withstands extreme heat, pressure, and exposure to diesel fuel and oil, significantly extending their service life compared to standard silicone hoses. The constant-tension T-bolt clamps maintain a reliable seal even under fluctuating boost conditions, preventing leaks and maintaining consistent performance.

Installation & Fitment:

This intercooler kit is designed for a direct bolt-in installation on Dodge Ram 2500 and 3500 trucks equipped with the 6.7L Cummins engine from 2009 to 2012. The kit fits a wide range of trims including Laramie, SLT, ST, SXT, Longhorn, Outdoorsman, and TRX models with various transmissions such as 48RE, 545RFE, 68RFE, AS68RC, and G56.

Installation requires no cutting, welding, or permanent modifications, making it accessible for experienced DIYers and professional installers alike. All necessary hardware, clamps, and silicone boots are included to ensure a straightforward upgrade process.
