Engineered specifically for 2003 through 2007 Ford F-250, F-350, F-450, F-550 Super Duty and Excursion models equipped with the 6.0L Powerstroke turbo diesel engine, the Banks Ram-Air Cold Air Intake System (42155) delivers substantial airflow improvements over the restrictive, non-serviceable factory Donaldson paper airbox. Factory intake configurations choke high-output diesel applications under heavy towing loads, raising exhaust gas temperatures and slowing turbo spool.

The Banks system features a fully enclosed, aerodynamic polymer air housing with oversized side and bottom inlets designed to draw dense, cold ambient air while locking out power-robbing engine bay heat. Unlike rigid aftermarket intakes that transmit engine vibration directly to mounting points, the Ram-Air kit utilizes a heavy-duty 4.5-inch flexible silicone bellows that accommodates engine torquing and chassis movement. Paired with an oversized washable filter, available in oiled cotton gauze or dry synthetic media and a streamlined giant-outlet intake duct, this kit sharpens throttle response and cuts smoke without setting trouble codes or requiring custom ECU tuning.

Key Features & Benefits

• Astonishing Airflow Volume: Outflows restrictive OEM airboxes by up to 64%, improving volumetric efficiency and reducing turbo lag.
• Lowers Operating EGTs: Inhales cooler outside air to lower exhaust gas temperatures and reduce smoke output during demanding towing pulls.
• 4.5-Inch Engine-Flex Bellows: Accommodates diesel engine movement and chassis flex under heavy torque loads, preventing broken brackets and tube fatigue.
• Oversized Lifetime Filter (Oiled or Dry): Large surface area traps fine dirt and dust without choking airflow, extending service intervals between cleanings.
• Trouble-Code Free Calibration: Precision-engineered MAF and sensor port geometry prevents check engine lights on factory stock or tuned trucks.
• 50-State Emissions Legal: CARB compliant under Executive Order D-161-80 for legal street use across all 50 states.

• Fitment Notice: Directly replaces the complete factory airbox and intake duct assembly. Retains factory sensor connections with zero cutting or splicing required.
• Installation Tip: Ensure the factory air filter restriction indicator (or an OEM replacement like the Motorcraft FA-1784) is securely seated into the Banks housing port before completing the intake tube clamping. Clean and re-oil the oiled cotton element, or wash the dry element, using Banks filter service products every 30,000 to 50,000 miles.
