For the 2003-2007 Ram 2500 or 3500 with the 5.9L Cummins engine and stock intercooler setup, the Monster-Ram Intake Elbow (42765) replaces the restrictive factory elbow and optimizes airflow from the intercooler. Designed to boost performance, throttle responsiveness, and engine efficiency.

Product Overview

This intake elbow upgrade increases boost and airflow without raising turbine back-pressure. The result: quicker throttle response, improved fuel efficiency, and better overall engine breathing.
