Maximize airflow, reduce turbo lag, and lower Exhaust Gas Temperatures (EGTs) on your 2003–2007 Dodge Ram 2500/3500 with the Banks Power Ram-Air Cold Air Intake System (42145). Engineered specifically for the 3rd Gen 5.9L Cummins, this system is CFD-designed (Computational Fluid Dynamics) and dynamically tested to outperform the restrictive factory airbox, delivering dense, high-velocity ambient air straight to your turbocharger.

Engineered for Superior Airflow and Density

The Banks Ram-Air system features a massive, enclosed filter housing and a wide-mouth air inlet that captures cool air from outside the engine bay. Inside, a giant, low-restriction reusable air filter maximizes filtering surface area while minimizing pressure drop. The computer-designed, seamless intake tube is meticulously tuned to eliminate sharp bends and turbulence, ensuring your 24-valve Cummins spools faster and pulls harder under heavy towing conditions.

Key Features & Benefits

• CFD-Optimized Airflow: Computer-designed intake duct and housing maximize air volume and velocity to reduce turbo spool times.
• Lower EGTs While Towing: Feeds cool, dense air to the engine to help keep exhaust gas temperatures safely managed under heavy loads.
• Enclosed Housing Design: Sealed air box blocks out hot engine bay heat to ensure only ambient outside air reaches the filter.
• Choice of Filter Media: Available with a high-capacity, washable oiled cotton media or a dry synthetic element for easy maintenance.
• Direct Bolt-On Fitment: Mounts securely using factory mounting points and includes heavy-duty hardware for a hassle-free installation.
