DDP 325-90NZ 5.9 Cummins 90HP 30% Over Fuel Injector Nozzle Set

Upgrade your 2004.5–2007 5.9L Cummins common-rail engine with the Dynomite Diesel DDP 325-90NZ injector nozzle set. These 30% over-stock flow nozzles deliver approximately +90 horsepower while remaining compatible with the factory CP3 pump, making them one of the largest recommended nozzle options for a stock pump or stock turbo setup.

Precision EDM-cut SAC-style nozzles with patented pilot-hole technology provide improved fuel atomization, better combustion efficiency, stronger mid-range pull, and sharper throttle response. With proper supporting modifications and custom tuning, they can support 600–650 RWHP.
