2003-2007 Cummins Compound Stock Add-A-Turbo Kit (227457)

Industrial Injection's Compound Add-A-Turbo Kit stacks a 75/96/1.32 atmosphere turbo on top of the factory turbo on a 2003-2007 5.9L Cummins. The kit was redesigned for easier installation, improved fitment, and lower EGTs, and includes a new dipstick tube and A/C retrofit line so nothing has to be bent or relocated during install.

Per Industrial Injection, the kit is capable of 650 hp with supporting fueling upgrades.
