DDP 305-50 Remanufactured 50HP Injector Set (15% Over) for 2003-2004 5.9L Cummins

Upgrade your 2003–2004 Dodge Ram 5.9L Cummins with a balanced set of remanufactured Dynomite Diesel (DDP) injectors that deliver a noticeable 50 rear-wheel horsepower increase while keeping excellent street manners, clean combustion, and everyday drivability.

These injectors use 15% over stock nozzles and Dynomite’s patented dual-pilot-hole SAC nozzle technology (2 pilots at 0.005", 6-hole design). The result is better fuel atomization, reduced smoke, improved throttle response, and frequently better fuel economy compared with worn stock injectors. They are designed to run safely on a completely stock truck.

Key Features

• Approximately 50 RWHP gain over stock
• 15% over stock fuel flow
• Remanufactured with new OE-spec wear components (new nozzles, control valves, seals, and critical internals)
• Flow-balanced and matched as a complete set for even cylinder-to-cylinder performance
• SAC nozzles with patented pilot-hole technology for cleaner, more efficient combustion
• Excellent street manners and typically improved MPG
• Safe for stock trucks and stock fuel systems
• Pyrometer recommended to monitor exhaust gas temperatures

Fitment

2003–2004 Dodge Ram 2500/3500 with 5.9L Cummins common-rail engine.

Notes

• Sold as a complete remanufactured set (core charge typically applies)
• A tuner or supporting modifications can help maximize the extra fuel, but they are not required for safe operation

These injectors give you a reliable, well-mannered power bump without the harshness or efficiency penalty of much larger injectors. Ideal for daily driving, light towing, and mild performance builds.
