Construction & Design

The Mishimoto intercooler kit is built with premium materials and precision engineering to withstand the rigors of heavy-duty use. The intercooler core features rugged cast aluminum end tanks paired with a bar-and-plate core, maximizing cooling efficiency and durability. Mandrel-bent aluminum piping with a 3-inch diameter ensures smooth airflow by eliminating restrictive bends and supporting high-volume air delivery without pressure loss.

Mishimoto’s exclusive DuraCore technology enhances the silicone boots with an innermost layer that resists heat, pressure, fuel, and oil exposure far better than standard silicone. This innovation extends the life of the boots and prevents leaks or blowouts, even under extreme operating conditions.

Performance & Sound

By lowering intake air temperatures by up to 12.5%, this intercooler kit helps your 6.7L Cummins engine maintain a denser air charge, which improves combustion efficiency and power output. Cooler intake air reduces the risk of heat soak during extended heavy use such as towing or off-road driving, ensuring consistent engine performance. While primarily focused on thermal management and airflow, the kit also contributes to smoother throttle response and supports higher power levels without compromising reliability.
