Mishimoto Intercooler Kit

2007.5–2009 Dodge / RAM 2500/3500 6.7L Cummins

Part #: MMINT-RAM-07KSL

Overview

The Mishimoto Intercooler Kit is a comprehensive upgrade designed specifically for the 2007.5 to 2009 Dodge and RAM 2500/3500 trucks equipped with the 6.7L Cummins engine. This kit is engineered to enhance your truck’s performance by improving airflow and significantly reducing air-charge temperatures. By lowering intake temperatures and exhaust gas temperatures (EGTs), the intercooler kit supports increased engine efficiency and durability across all power levels.

Ideal for diesel enthusiasts and professionals seeking reliable power gains and improved thermal management, this kit delivers cooler, denser air to the engine, which translates into better combustion and overall performance.

Key Features

This intercooler kit combines advanced engineering and durable materials to optimize your truck’s performance and reliability. Key features include:

• High-flow mandrel bent 3.5-inch aluminum intercooler piping with a polished finish for smooth, unrestricted airflow
• Mishimoto silicone boots featuring DuraCore technology for superior resistance to heat, pressure, fuel, and oil
• Constant-tension T-bolt clamps that ensure a secure, leak-free connection under all conditions
• Bar-and-plate intercooler core with significantly increased volume compared to factory units for improved cooling capacity
• Durable cast aluminum end tanks engineered to withstand high boost pressures and thermal cycling
• Reduced pressure drop across the intercooler for enhanced engine efficiency and power delivery
• Available with a silver core finish to complement your engine bay aesthetics
• Backed by Mishimoto’s signature lifetime warranty for long-term peace of mind

Construction & Design

The Mishimoto intercooler kit is built with premium materials and precision engineering. The intercooler piping is crafted from mandrel bent 3.5-inch aluminum, which maintains consistent diameter through bends to maximize airflow and minimize turbulence. The polished finish not only looks great but also resists corrosion.

The silicone boots incorporate Mishimoto’s proprietary DuraCore technology, a synthetic inner layer that dramatically improves resistance to extreme heat, pressure, fuel, and oil exposure. This innovation extends the life of the boots by preventing leaks and blowouts common in lesser-quality silicone hoses.

The intercooler core utilizes a robust bar-and-plate design, which offers superior heat dissipation compared to tube-and-fin cores. Cast aluminum end tanks provide strength and durability, ensuring the intercooler withstands the rigors of heavy-duty use and high boost pressures.
