The Ram 6.7 EGR Upgrade kit re-routes coolant to the back of the head between Cylinders 5 and 6 to help circulate coolant to the areas that get the hottest. 

This kit completely removes the EGR Cooler, Crossover Tube and Actuator to clean up the engine bay and eliminate soot buildup in the intake tract, and includes a throttle valve delete to free up airflow.

Made by Pro Power Diesel in the USA.
