Banks Power Monster-Ram Intake System

2007.5–2012 RAM 3500/4500/5500 Chassis Cab 6.7L Cummins

Part #: 42806-N

Overview

The Banks Monster-Ram Intake System is a high-performance upgrade designed specifically for the 2007.5 to 2012 RAM 3500, 4500, and 5500 Chassis Cab trucks equipped with the 6.7L Cummins engine. This intake system dramatically improves throttle response and fuel economy by eliminating airflow restrictions inherent in the factory design. By replacing the restrictive stock heater grid with Banks’ high-flow billet intake plate and innovative heater design, the Monster-Ram ensures smoother, unrestricted airflow to the engine.

Ideal for diesel enthusiasts and professionals seeking enhanced engine efficiency and durability, the Monster-Ram not only boosts airflow but also prevents severe engine damage caused by the stock heater grid failure. It is the only RAM intake elbow compliant with 50-state emissions regulations, making it a reliable and legal upgrade for all users.

Key Features

The Monster-Ram Intake System incorporates advanced engineering and cutting-edge technology to deliver superior performance and reliability. Key features include:

• Flows 72.7 lbs/min MAF with Banks’ High-Flow Heater and Billet Intake Plate, nearly doubling the stock flow of 38.6 lbs/min MAF
• Eliminates the restrictive stock heater grid plate, preventing potential engine damage
• Vertical coil-style high-flow heater provides effective cold start functionality without obstructing airflow
• Raises boost pressure without increasing backpressure at the turbine for improved engine responsiveness
• Direct replacement aluminum casting designed for instant power and acceleration gains
• Newly engineered No. 1 fuel line allows for a more direct and unrestricted airflow path
• Four 1/8” NPT ports for easy installation of temperature and pressure sensors, ideal for data acquisition and tuning
• Tested extensively using computational fluid dynamics (CFD), flow bench, dyno, and real-world driving conditions
• 50-state emissions compliant, making it legal for use across the United States
• Outperforms all competitors by more than double in airflow improvement

Construction & Design

The Monster-Ram is crafted from high-quality aluminum casting, ensuring durability and heat resistance under demanding conditions. Banks Power engineers utilized advanced computational fluid dynamics (CFD) to optimize the intake elbow’s shape, eliminating turbulence and airflow obstructions common in the factory design. The billet intake plate replaces the stock heater grid, removing a major bottleneck in the airflow path. The innovative vertical coil-style heater maintains essential cold start functionality while allowing maximum airflow, a design not found in any other intake system.

Additionally, the system includes a redesigned No. 1 fuel line that frees up space within the intake elbow, enabling a straighter, less restrictive airflow path. This thoughtful engineering results in a more efficient and responsive engine breathing system.

Performance & Sound

The Monster-Ram Intake System significantly enhances engine performance by increasing airflow capacity and reducing intake restrictions. This results in improved throttle response, increased boost pressure without added backpressure, and better fuel economy. Drivers will notice quicker acceleration and a more efficient power delivery, especially under heavy load or towing conditions. While primarily focused on airflow and performance, the system also contributes to a cleaner, more efficient engine operation.

Installation & Fitment

Designed as a direct replacement for the factory intake elbow, the Monster-Ram installs easily on 2007.5–2012 RAM 3500, 4500, and 5500 Chassis Cab trucks with the 6.7L Cummins engine. The installation requires no permanent modifications, and Banks provides all necessary hardware. The redesigned No. 1 fuel line included in the kit ensures a proper fit and optimal airflow. Installation can typically be completed with basic hand tools and mechanical knowledge.
