The Banks Monster-Ram is the best-engineered intake elbow (horn) available for the 2019-2024 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 Bank's 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 Banks' 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.
