Construction & Design

The Banks Techni-Cooler system is engineered with precision and durability in mind. The intercooler core is 20% thicker than stock, providing a substantial increase in cooling surface area and flow volume. The end tanks are crafted from custom-machined, high-quality aluminum castings that resist corrosion and withstand high boost pressures. Mandrel-bent 3.5-inch boost tubes ensure smooth airflow transitions, minimizing turbulence and pressure drop. The Monster-Ram intake manifold is designed to complement the intercooler by delivering a super-flow of air, further enhancing engine breathing and performance.

Performance & Sound

By dramatically increasing the cooling capacity and reducing intake air temperatures, the Banks Intercooler Upgrade enables your Cummins engine to produce more power continuously without overheating. Cooler, denser air improves combustion efficiency, resulting in better throttle response, increased torque, and improved fuel economy. Additionally, lower exhaust gas temperatures reduce engine wear and help maintain optimal performance under heavy loads or extended driving conditions.

Installation & Fitment

This intercooler upgrade is designed as a direct fit for 2006 and 2007 Dodge Ram 2500 and 3500 trucks equipped with the 5.9L Cummins engine. Installation is straightforward with included mounting hardware, requiring no major modifications. The system replaces the stock intercooler and boost tubes, making it an ideal upgrade for owners seeking enhanced performance with minimal installation complexity.
