DDP 305-50NZ 5.9 Cummins 50HP Fuel Injector Nozzle Set (15% Over)

Unlock more performance from your 2003–2004 5.9L Cummins with this Dynomite Diesel 15% over nozzle set. These SAC-style nozzles increase fuel flow by 15% compared to stock, delivering approximately 50 rear-wheel horsepower while preserving smooth street manners and everyday drivability.

The nozzles use patented dual-pilot-hole technology (two 0.005" pilots) for improved fuel atomization and more complete combustion. The result is stronger throttle response, better towing capability, and the potential for improved fuel economy on a stock or mildly modified truck.

This is a complete matched set designed as a cost-effective upgrade when your existing injector bodies are in good condition. It is safe for use on otherwise stock 5.9L common-rail engines.
