Improve airflow to your 2007.5-2018 Dodge 6.7L Cummins with the Banks Power 42790 4" Monster-Ram Intake. The Monster Ram flows 1008 cfm (77.01 lbs/min) compared to stock's measly 432 cfm (33.00 lbs/min). The Monster-Ram also raises boost without increasing backpressure at the turbine. This results in a more responsive, power efficient engine. 

The Monster-Ram Intake accommodates stock mounting points including Temperature and Pressure sensors, and the wiring harness and dipstick tube. The factory inlet is cramped and angular compared to Banks' larger, streamlined cast-metal Monster-Ram. It's the perfect upgrade whether you're just starting out or working to build a serious, purpose-built race machine. 

The sky is the limit for performance expandability when it comes to adding water-methanol, propane, or nitrous injection. The Monster Ram features up to (4) 1/8" NPT ports for flexibility, the top two ports are positioned to allow for proper atomization directly into the center of the air mass while preventing wall wetting.

  • (4) 1/8" NPT Ports 
  • 4" CNC Machined Inlet
  • Increased Throttle Response
  • Larger & Less Restrictive Than Stock
  • Includes Fuel Line For Easy Installation  
Application Notes: 
Includes 4" to 3.5" Hump Hose. 
This manifold will not fit the stock boost tube.
This manifold puts inlet hose joint at the stock location. 
Aftermarket tuning and other supporting modifications are required for installation.
