- Nozzles flow-matched to ~1% per set; injectors matched to ~3% (per set)
- Injection profiles aligned; spec matched to nozzle flow
- Internal body modifications used on extreme sizes for proper rate shaping
- New bodies (no reman mixing), built for 6.7C applications
Fitment
- 2007.5–2018 Dodge Ram 2500/3500, 6.7L Cummins 24V (common-rail)

- Core policy applies. Contact CPP Diesel for core handling and return timeline.
- Professional installation and calibration recommended.
Recommended Parts
- High-flow lift pump (AirDog/FASS)

400% sets support extreme horsepower builds with large turbo(s), high-flow CP3(s), and competition-grade fuel supply. Street-only trucks typically do not require this size.
Do I need a lift pump and upgraded CP3 with these?
Yes. A constant, clean fuel supply and adequate high-pressure pump capacity are required to maintain rail pressure and prevent injector damage.
Are these new injectors and are they flow-matched?
Yes—this set uses brand-new bodies and SAC nozzles. Sets are flow-matched to tight tolerances for consistent cylinder-to-cylinder delivery.
Can these be daily driven?
These are built for competition/maximum fueling. With proper supporting mods and calibration, drivability is possible, but they are not recommended for typical daily-driver use.
Is a core charge required?
Yes. Core returns are required per manufacturer policy. Contact CPP Diesel for current core amount and instructions.
