Engineered Air Density and Factory Battery Retention

Engineered specifically for the 2017–2019 Ford Super Duty platform equipped with the 6.7L Powerstroke V8 turbo diesel, the Banks Ram-Air System (41890) overcomes the restrictive packaging of the front passenger battery tray without requiring dangerous firewall relocation brackets. By channeling cool ambient air above and below the stock battery position through aerodynamic ducting, Banks feeds dense, oxygen-rich air directly to the turbocharger compressor inlet. The system centers around a massive 1,065 square inch multi-layer oiled cotton gauze filter element that delivers 99% filtration efficiency and an air density gain of 40% over the OEM intake tract.

Key Features & Benefits

• 40% Air Density Gain: CFD-engineered and dyno-proven to pack higher air mass into the cylinders, sharpening throttle response, reducing turbo lag, and lowering EGTs under heavy towing loads.
• Factory Battery Position Retained: Avoids firewall bracket modifications or hanging heavy battery weight over the engine bay, maintaining stock safety and service access.
• Massive Oiled Cotton Filter: Provides 1,065 sq. in. of active filtration surface area, flowing unrestricted CFM while capturing abrasive dust particles with washable, lifetime reusability.
• Dual Cold-Air Induction Paths: Features a forward-facing inlet designed to integrate with the OEM radiator support scoop alongside a secondary ambient air inlet.
• EPDM Rubber Bellows Elbow: Heavy-duty rubber elbow with molded bellows absorbs engine torque flex and features an integrated coolant hose rest to prevent abrasive rubbing.
