Serious flow, precise control. This brand-new set of six S&S Diesel Motorsport injectors delivers 100% over nozzle flow for the Early 5.9 common rail platform (2003–2004). Built with SAC nozzles and matched using OE-level standards, these injectors are engineered for clean, repeatable fueling under load.
- SAC nozzles with proprietary honing for clean, consistent holes
- Nozzles flow-matched to ~1% per set; injectors matched to ~3% (per S&S technical details)
- Injection profiles aligned; spec matched to nozzle flow size
- Brand-new bodies (not reman) for this specific part number

Helpful Notes
- Tuning & supporting mods required: 100% over injectors demand adequate air (turbo) and appropriate calibration for best drivability.
- Core policy: S&S lists core returns on many injector options; verify if a refundable core applies to your order.
- Warranty: S&S injectors are supported by S&S Motorsport warranty terms.
It refers to the nozzle flow increase versus stock. Real-world fuel output depends on rail pressure and injection duration, so the horsepower gain is not a strict +100% but the flow increase is a solid sizing reference.
Yes. 100% over injectors require more airflow and proper calibration to maintain EGT control, smoke management, and drivability.
This specific part number is a brand-new injector set. If you are searching for reman options, see our Cummins injector category for alternatives.
No. These are for the Early 5.9 (2003–2004). Late 2004.5–2007 trucks use a different injector spec—shop our Late 5.9 options instead.
It’s strongly recommended to install new feed tubes with new injectors to ensure proper sealing and prevent contamination.
