Engineered Air Density and Factory Battery Retention

Engineered specifically for the 2017–2019 Ford Super Duty platform powered by the 6.7L Powerstroke V8 turbo diesel, the Banks Power Ram-Air System (41890-D) solves the airflow challenges unique to this engine bay layout. Unlike aftermarket designs that require hazardous battery relocation brackets, Banks keeps the heavy passenger-side battery locked securely in its factory tray while routing cool ambient air around and under the battery. The system centers on an oversized dry synthetic filter boasting 733 square inches of active filtration area, delivering a verified 40% air density gain over stock to improve torque, reduce exhaust gas temperatures, and enhance fuel economy.

Key Features & Benefits

• 40% Air Density Gain: Engineered and flow-bench validated to channel cold, dense ambient air to the turbo compressor wheel for faster spool-up and lower EGTs.
• Retains Stock Battery Tray: Preserves factory crash safety and front-end weight distribution by fitting cleanly behind the battery with zero firewall bracket modifications.
• Large Dry Synthetic Filter Element: 733 sq. in. of multi-layer synthetic media provides 99% filtration efficiency without requiring filter oils or solvents.
• Dual Inlet Cold-Air Path: Combines an integrated front-facing OEM air inlet with a secondary auxiliary scoop to pull the coolest air possible into the housing.
• EPDM Silicone Bellows Coupler: Molded with integrated expansion bellows and an engineered coolant hose rest to accommodate engine torque flex and eliminate tube fatigue.
