Construction & Design:

The Mishimoto intercooler kit is built with durability and performance in mind. The intercooler core features cast aluminum end tanks that resist cracking and warping under high thermal stress. The bar-and-plate core design maximizes cooling efficiency by increasing surface area and airflow through the core.

The intercooler piping is crafted from mandrel-bent aluminum tubing, which maintains a consistent 3-inch diameter to minimize airflow restrictions. This polished aluminum piping not only improves airflow but also adds a clean, professional look under the hood. The silicone boots incorporate Mishimoto’s proprietary DuraCore technology, providing 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 denser, cooler air charge for improved combustion efficiency. Cooler air intake temperatures translate to more consistent power delivery, reduced risk of heat soak, and enhanced engine reliability during heavy towing or high-performance driving. While the kit primarily focuses on thermal management and airflow, it also contributes to smoother throttle response and optimized turbocharger performance.

Installation & Fitment:

The Mishimoto Silver Intercooler Kit is designed as a direct-fit upgrade for the 2013–2018 Ram 2500 and Ram 3500 models equipped with the 6.7L Cummins engine.
