2003–2009 Dodge Ram 2500 / 3500 5.9L & 6.7L Diesel, 2008–2009 Ram 1500 6.7L Diesel

Part #: MMINT-RAM-03SL

The Mishimoto Intercooler is a precision-engineered upgrade designed specifically for Dodge Ram 2500 and 3500 trucks from 2003 to 2009 equipped with 5.9L and 6.7L Cummins diesel engines, as well as the 2008–2009 Ram 1500 with the 6.7L diesel. This intercooler enhances intake air cooling and airflow, resulting in lower intake temperatures and reduced pressure loss. It is ideal for both stock and moderately modified trucks, helping to improve engine efficiency, support higher boost pressures, and reduce exhaust gas temperatures (EGTs). Whether you’re towing heavy loads or pushing your truck’s performance limits, this intercooler provides reliable, long-lasting performance.

Key Features

Combining advanced design with durable materials, the Mishimoto Intercooler delivers superior cooling and reliability for your Cummins-powered Dodge Ram. Key features include:

• Robust cast aluminum end tanks for enhanced strength and resistance to cracking under high boost conditions
• Dense bar-and-plate core design that maximizes heat dissipation and airflow efficiency
• Increased core volume to support substantial boost pressures and reduce intake air temperatures
• Larger outlet ports compared to factory units for improved airflow and minimized pressure drop
• Two silicone boots featuring Mishimoto’s DuraCore technology for superior resistance to heat, pressure, fuel, and oil exposure
• Signature constant-tension T-bolt clamps ensuring consistent and durable holding power
• Attractive silver finish that complements the engine bay aesthetics
• Backed by Mishimoto’s lifetime warranty for peace of mind and long-term durability

Construction & Design

The Mishimoto Intercooler is constructed with high-quality cast aluminum end tanks that provide exceptional durability and strength, preventing cracking even under demanding boost conditions. Its core features a dense bar-and-plate design, which is proven to offer superior heat dissipation and airflow compared to traditional tube-and-fin cores. This design effectively lowers intake air temperatures, which is critical for maintaining optimal engine performance and preventing detonation. The intercooler’s larger core volume and outlet ports reduce pressure loss, allowing your turbocharger to operate more efficiently and consistently.

The included silicone boots utilize Mishimoto’s proprietary DuraCore technology, incorporating a synthetic inner layer that significantly enhances resistance to extreme heat, pressure, and exposure to fuel and oil. This construction extends the life of the boots, preventing leaks and blowouts, and ensuring a secure seal under all operating conditions.

Installation & Fitment

This intercooler is a direct-fit replacement designed specifically for the following vehicles: 2003–2007 Dodge Ram 2500 and 3500 with 5.9L diesel engines, 2007–2009 Dodge Ram 2500 and 3500 with 6.7L diesel engines, and 2008–2009 Ram 1500 with 6.7L diesel. Installation is straightforward and requires no permanent modifications to your truck. The kit includes all necessary silicone boots and clamps, allowing for a seamless swap with the factory intercooler. This makes it an excellent upgrade for enthusiasts seeking improved performance and reliability without the hassle of custom fabrication.
