The best intake in its class. Designed for maximum air density gain giving you more power and better mileage. Proprietary filter sleeve provides superior airflow with best in class performance. Largest and least restrictive filter in its class. Unparalleled dirt capacity for more miles between cleaning. Retains stock battery location.
When Banks engineers set out to design a Ram-Air intake for the 2017-19 Ford 6.7L Super Duty, they had one seemingly impossible challenge: to achieve higher air density at the turbo inlet than all competitors while keeping the airbox in the stock location behind the battery. As Power Stroke owners know, the battery is located near the front corner of the engine bay. This means air must pass above and/or below the battery to the airbox behind it. One of the competitors chose to relocate the battery by having the customer attach a piece of supplied angle-iron to the thin firewall, cantilevering it over the engine. In our opinion, the battery is much too heavy and poses a danger if it were to break loose and fall. After all, many trucks see off-road conditions. These requirements would set our Mechanical Engineering team on a year-long mission of design, research and development, and on and off-road testing.

Performance between intakes was calculated comparing the delta density (lb/1kft3) from ambient air to compressor inlet air as seen in the graph above. Density takes into account temperature, pressure, and humidity. The greater the air density, the more horsepower your engine will make. Yes, flow is important, but if the system flows more air, and that air is hot, you’ll often see a loss in horsepower. High-flow, cool, dense air is the winning combination. For a better understanding of Air Density, see this article.
The new Ram-Air system draws cool air from two key locations; the stock hood scoop and a down-facing inlet. Why not utilize the stock fender opening? Testing revealed it to be a source of hot air, not the cool air Banks engineers were searching for. Once the sensors were installed, testing began.
S&B Intake instrumentation — Note this intake draws air from 3 locations: Ch-1A front intake scoop, Ch-1B Battery side foam inlets, Ch-1C Fender side inlet. S&B provides a plug to close the fender side inlet; therefore, it was tested with and without.
AFE Intake instrumentation — Note this intake draws air from one location and splits the airflow. Ch-1A front intake scoop, Ch-1B stock passage underneath the battery.
Stock Intake Instrumentation — Note that the stock intake draws air from one location; the front intake scoop, and directs it underneath the battery into the airbox. There is another foam inlet where some minor airflow does occur, facing the engine bay, as seen in the photos.
Based on testing, the Banks Ram-Air system performed best thanks to its lack of restriction and minimal air-temperature increase, making it the air density king. And as racers know, air density means horsepower and efficiency.
