Dynomite Diesel DDP67-300 Reman Injector Set — 100% Over for 2007.5–2018 6.7L Cummins

Unlock the performance potential of your 6.7L Cummins with the Dynomite Diesel 67-300 remanufactured injector set. This complete set of six injectors flows 100% over stock to deliver the extra fuel needed for serious power, supporting up to 950 horsepower when paired with the proper supporting modifications.

Each set is precision remanufactured, flow-tested, and sold as a balanced and matched group (typically within 1%) so every cylinder receives a consistent fuel charge. The result is smoother power delivery, better cylinder-to-cylinder balance, and a more reliable foundation for high-output builds.

These injectors use high-performance SAC-style nozzles with Dynomite’s patented dual-pilot-hole technology (two 0.005" pilots) and a 6-hole design. The small pilots improve atomization at lower rail pressures and idle, while the main orifices take over under load for strong, efficient combustion.
