Don't waste your money and time on any other intercooler other than Banks for your 2003-2007 Dodge Cummins 5.9L. Banks Techni-Cooler Intercooler System replaces those stock plastic end tanks with all-aluminum end tanks, which will never melt or burst under very high boost. With this kit you also receive 3.5″ boost tubes to help your turbo spool faster and increase flow to your engine. With a 20% bigger core and Monster-Ram intake manifold flow volume has increased by 27%.
