Mishimoto Intercooler
2003–2009 Dodge / RAM 2500/3500 5.9L/6.7L Cummins
Part #: MMINT-RAM-03SL
Overview
The Mishimoto Intercooler is engineered specifically for the 2003 to 2009 Dodge and RAM 2500/3500 trucks equipped with the 5.9L and 6.7L Cummins inline-6 engines. Known for their durability and smooth power delivery, these Cummins engines benefit greatly from enhanced intake cooling and airflow. This intercooler is designed to lower intake air temperatures, reduce pressure loss, and improve overall engine efficiency, making it an ideal upgrade for both stock and modified trucks.
Whether you are looking to maintain your truck’s reliability or push your performance limits, the Mishimoto intercooler offers a robust solution that supports higher boost pressures and helps lower exhaust gas temperatures (EGTs), contributing to improved engine longevity and power consistency.
Key Features
This intercooler combines advanced engineering with durable materials to deliver superior performance and reliability. Key features include:
- Robust cast aluminum end tanks for enhanced strength and durability
- Dense bar-and-plate core design that maximizes cooling efficiency and airflow
- Increased core volume to support substantial boost pressures and reduce intake temperatures
- Larger outlet ports compared to factory units for improved airflow and reduced pressure drop
- Two silicone boots featuring Mishimoto’s DuraCore technology for superior resistance to heat, pressure, fuel, and oil
- Signature constant-tension T-bolt clamps ensuring consistent and durable holding power
- Available in silver finish to complement your engine bay aesthetics
- Backed by Mishimoto’s lifetime warranty for long-term peace of mind
Construction & Design
The Mishimoto intercooler is built with high-quality cast aluminum end tanks that provide exceptional strength and resist cracking under high boost conditions. The core utilizes 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 choice ensures that intake air temperatures are minimized, which is critical for maintaining engine performance and preventing detonation.
The intercooler’s larger core volume and outlet ports are engineered to reduce pressure loss, allowing your turbocharger to operate more efficiently. The included silicone boots are constructed with DuraCore technology, a synthetic inner layer that significantly improves resistance to extreme heat, pressure, and exposure to fuel and oil, extending the life of the boots and preventing leaks or blowouts.
Installation & Fitment
The Mishimoto intercooler is a direct-fit replacement designed specifically for the 2003–2009 Dodge and RAM 2500/3500 trucks with 5.9L and 6.7L Cummins engines. Installation is straightforward and requires no permanent modifications to your vehicle. The package 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 without the hassle of custom fabrication.
What's Included
- Mishimoto cast aluminum intercooler core with end tanks
- Two DuraCore silicone boots
- Two constant-tension T-bolt clamps
- Installation hardware and instructions
Ideal For
This intercooler is perfect for Dodge and RAM 2500/3500 owners who want to enhance the performance and reliability of their 5.9L or 6.7L Cummins engines.

What does the Available to Promise date mean?
ETA stands for Estimated Time of Arrival. The date shown is calculated using our Available-to-Promise (ATP) system, which tracks real-time supplier commitments to determine when a product is expected to be available for delivery. Specifically, the date is calculated by adding 9 business days from the date a supplier has committed to ship the product, representing a worst-case scenario for when we can expect to receive inventory.
Please note: The ETA is an estimate, not a guarantee. While we work closely with our suppliers to keep dates as accurate as possible, delays due to shipping carriers, weather, customs, or supplier-side issues may occasionally push the actual arrival beyond the date shown. Likewise, inventory may arrive sooner than the ETA in many cases. If you would like to be notified for when this item arrives, sign up for our back in stock notifications!
