Engineered specifically for 3rd Generation (2007.5–2009) Dodge Ram 2500 and 3500 trucks powered by the 6.7L 24-Valve Cummins turbo diesel, the Banks Power Ram-Air Cold Air Intake System (42175) delivers maximum mass air density directly to the Holset variable-geometry turbocharger (VGT). The factory air cleaner and restrictive corrugated ducting introduce turbulence and soak up under-hood heat; Banks replaces them with an aerodynamic, fully enclosed roto-molded airbox with oversized side and bottom inlets designed to draw cool, dense ambient air while shielding against high engine temperatures.

The kit centers on a massive multi-layer oiled cotton gauze dome filter that provides maximum airflow and heavy-duty dust retention, with washable, reusable durability for the vehicle's lifespan. To withstand the torque vibration of the 6.7L Cummins inline-six, Banks integrates an exclusive 4.5-inch flexible EPDM rubber bellows coupler that absorbs engine movement, protecting the airbox mounting tabs, tube joints, and turbo inlet seals from mechanical fatigue.

Key Features & Benefits

• 50% Airflow Improvement: Outflows the factory intake tract by up to 50%, supplying colder and denser oxygen charges to improve throttle response, increase pulling power, and lower exhaust gas temperatures (EGTs).
• Multi-Layer Cleanable Oiled Cotton Media: Washable and reusable red oiled cotton filter element provides high-capacity particulate filtration and long-term reusability across heavy towing cycles.
• Thermal Heat-Shielded Enclosure: Fully sealed roto-molded polymer airbox keeps out hot engine compartment air, maintaining lower intake air temperatures (IATs) under sustained load.
• 4.5-Inch Flexible Bellows Coupler: Absorbs engine rocking and high-torque vibration, preventing cracked ducting, broken mounting brackets, and coupler pop-offs.
• Factory Sensor Integration: Retains factory mass airflow (MAF) and temperature sensor mounting locations and flow parameters to ensure error-free operation without check engine lights.
• Direct Bolt-On Installation: Mounts straight to the factory 3rd Gen chassis locations using basic hand tools without requiring cutting, trimming, or drilling.
