The Banks Power 42765 Monster-Ram Intake Manifold for your 2003-2007 Dodge 5.9L Cummins provides your engine with increased airflow. Maximum power, performance and efficiency are the ultimate goals, but to make it all happen the engine has to breathe freely and without needless restrictions. Finding ways to pump your engine full of cooler, denser air has always been the key. Our High-Ram intakes have always whipped the competition. Our new Monster-Ram flat-out destroys it. Utilizing the latest in electronic computational fluid-dynamic technology, tested on the flow bench as well as on the dyno, and finally proven in the real world where the rubber meets the road, Monster-Ram is a beast that only Banks could have unleashed. A simple, direct-replacement casting, Monster-Ram is instant power, performance and acceleration gratification. It's the perfect upgrade whether you're just starting out or working to build a serious, purpose-built machine. And with its up to six ports for water/meth/propane/nitrous injection (or pressure/temp. sensors), the sky's the limit for performance expandability.Â Features: 3" InletÂ CARB EO# D-161-107 Uses Factory Intercooler PipeÂ Increase Flow, Response & PerformanceÂ CA Residents: CARB E.O.
