The 2003-2007 5.9L Cummins Trucks

Joining the Duramax with its new Bosch common rail fuel injection system these Cummins gained more power, better emissions, and less smoke output.  They are exceptionally responsive to fuel and turbo upgrades.. the transmissions are usually the weak point behind this last generation 5.9L Cummins.
