Unlock serious power from your 2004.5–2007 5.9L Cummins with the Dynomite Diesel (DDP) 325-120 remanufactured injector set. These 45% over injectors deliver approximately 120 horsepower and enough fuel to support up to 900 RWHP when paired with the right supporting modifications.

Each set is remanufactured to tight tolerances using quality OE components, then precision balanced and flow-matched as a complete set of 6. This helps deliver even cylinder contribution, smoother operation, and reliable performance under high demand.
