Construction & Design

The Mishimoto intercooler kit is built to withstand the rigors of high-performance diesel applications. The intercooler core features rugged cast aluminum end tanks that resist cracking and warping under extreme thermal stress. Its bar-and-plate core design maximizes cooling efficiency by increasing surface area and optimizing airflow through the core.

Intercooler piping is crafted from mandrel-bent aluminum tubing, maintaining a consistent 3-inch diameter to minimize airflow restrictions and turbulence. The polished aluminum finish not only enhances airflow but also adds a clean, professional appearance under the hood. The silicone boots utilize Mishimoto’s DuraCore technology, offering superior durability against heat, pressure, and chemical exposure compared to standard silicone hoses.

Performance & Sound

By lowering intake air temperatures by approximately 12.5%, this intercooler kit helps your 6.7L Cummins engine maintain a denser, cooler air charge for improved combustion efficiency. Cooler intake air results in more consistent power delivery, reduced risk of heat soak, and enhanced engine reliability during heavy towing or spirited driving. While primarily focused on thermal management and airflow, the kit also contributes to smoother throttle response and optimized turbocharger performance.
