The Banks Monster-Ram is the best-engineered intake elbow (horn) available for the 2013-2018 RAM Cummins 6.7L. Gain responsiveness and power efficiency. Improve Mass Air Flow by 88 percent over the stock intake. Prevents grid heater bolt failure. What it does
The Monster-Ram improves airflow from the intercooler. It flows 72.7 lbs/min MAF (Mass Air Flow) with Banks’ High-Flow Heater and Billet Intake Plate compared to stock’s 38.6 lbs/min MAF.
Monster-Ram raises boost without increasing backpressure at the turbine. The result is a more responsive, power-efficient engine that offers even more headroom than stock for higher horsepower applications.
The complete system
Bank’s High-Flow Heater and Billet Intake Plate complete the perfect system. The High-Flow Heater allows for the removal of the restrictive stock heater grid plate. The new vertical coil-style heater provides the same functionality for cold starts as the stock grid heater but without obstructing airflow. Replacing the restrictive stock grid heater plate with the Banks High-Flow Intake Plate removes all obstructions and turbulence in the airflow path.
How it was designed
Utilizing the latest in CFD (computational fluid-dynamics), tested on the flow bench, the dyno, and on-road, Monster-Ram is a beast that only Banks could have unleashed. A direct-replacement aluminum casting, Monster-Ram is instant power, performance, and acceleration gratification. The factory inlet elbow is cramped and angular in order to accommodate the path of the stock No. 1 fuel line. Banks Engineers designed a new No. 1 fuel line, allowing the Monster-Ram to flow more air without obstruction.
Expandable
With four 1/8 inch NPT ports, perfect for temperature and pressure sensors, the sky’s the limit for data acquisition.
Beats the competition
Like all Banks products, the Monster-Ram was tested against all available competitors. It more than doubles the improvement over the closest competitor.

Beats stock and the competition. New over-sized filter element protects engine and outflows competition. Enclosed housing keeps out hot, power-robbing engine air. Reduces soot output, decreasing the frequency between regens.
Add an additional +20 hp to your 2017-2019 Duramax. Or, combine with the Derringer inline tuner for a total gain of 81 hp. Beats stock and the competition. New over-sized filter element, largest in its class, protects engine and outflows competition. Enclosed housing keeps out hot, power-robbing engine air. More airflow increases the air-fuel ratio allowing the engine to run more lean, reducing soot output, decreasing the frequency between regens. US Patent #10,138,851 B2

Combine with the Derringer inline tuner for a total gain of 81 hp. Does not work with Banks Intake Resonator Delete.

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.
