2009 Cummins Banks Intercooler Upgrade Kit

The Banks 25985 performance system is designed to enhance airflow, throttle response, and overall engine efficiency for compatible diesel applications. Developed by Banks Power, this system replaces restrictive factory intake components with a higher-flowing design that allows the engine to breathe more freely under all driving conditions.

By improving airflow delivery to the engine, the system supports more efficient combustion, resulting in stronger low-end response, smoother acceleration, and more consistent power output. These gains are especially noticeable during towing, hauling, and sustained highway driving, where intake restriction can limit performance and increase engine strain.
