DDP 305-90NZ 90HP Fuel Injector Nozzle Set (30% Over) – 2003-2004 5.9L Cummins

Upgrade your 2003-2004 5.9L Cummins with the DDP 305-90NZ 90HP Fuel Injector Nozzle Set. This complete nozzle set from Dynomite Diesel Products is engineered to deliver a significant increase in fuel flow and atomization. The 30% over nozzles provide approximately +90 rear-wheel horsepower while supporting up to 600–625 RWHP on a stock CP3 pump (more power is possible with a larger CP3). They are the largest nozzles typically recommended for use with a stock CP3 pump or stock turbo, making them an excellent choice for street performance, towing, and moderate power builds.

The nozzles feature SAC-style construction with patented pilot-hole technology (two 0.005" pilots plus 6 main holes) for improved fuel atomization, better combustion, reduced smoke, and consistent performance.
