2003-2007 Cummins Add-A-Turbo To Phatshaft W/ S475 Turbo Kit (227403)

Industrial Injection's Add-A-Turbo kit converts an existing 2003-2007 5.9L Cummins running a Phatshaft into a compound setup by stacking a BorgWarner S475 (75/96/1.32) as the atmosphere turbo. Designed for trucks already running larger injectors and ready to step up airflow.

• BorgWarner S475 turbo (75/96/1.32)
