DDP 305-ECO Economy Series Remanufactured Injector Set – 2003-2004 5.9L Cummins

Give your 2003-2004 Dodge Ram 5.9L Cummins a smart, street-friendly upgrade with the Dynomite Diesel (DDP) 305-ECO Economy Series remanufactured injector set. These injectors deliver a mild 10-20 RWHP gain, smoother operation, sharper throttle response, and better fuel economy—without the smoke, rattle, or extra mods that come with bigger injectors.

DDP rebuilds these injectors using OEM-quality components and flow-matches the complete set for consistent cylinder-to-cylinder fueling. They replace the factory 8-hole VCO nozzles with more durable 6-hole SAC-style nozzles (featuring DDP’s K-Factor technology). The result is cleaner atomization, reduced injector rattle on acceleration, lower EGTs, and little-to-no visible smoke.
