DDP 67-90NZ 90HP Fuel Injector Nozzle Set (25% Over) for 6.7L Cummins

Unlock more power, better atomization, and improved drivability from your 6.7L Cummins with the Dynomite Diesel (DDP) 67-90NZ injector nozzle set. These remanufactured SAC-style nozzles flow 25% over stock and are designed to deliver approximately 90 additional horsepower while supporting 575–650 RWHP on a stock CP3 pump (more with a larger pump).

• Balanced and matched set of 6 nozzles
• Includes new copper washers and injector hold-down/removal tool
• Largest nozzles recommended for stock CP3 or stock turbo applications

Benefits

• Stronger mid-range and top-end power
• Smoother idle and better throttle response
• Improved combustion efficiency

• Reliable performance from daily driving to modified builds

Fitment

2007.5–2018 Dodge/Ram 2500, 3500, 4500, and 5500 with 6.7L Cummins.

Important Notes

Professional installation and injector calibration are required. These oversized nozzles must be installed by a shop experienced with calibrating them. Label each injector and return it to the same cylinder. Do not lose the small steel disks located under the nozzles.

This set is a mechanical upgrade that adds reliable fuel delivery without relying solely on electronic tuning. Pair with proper supporting modifications (tuning, fuel supply, and exhaust) to realize the full potential.
