Thumbnail Filmstrip of 5.9 Cummins 350% Over Reman Injector S&S Diesel 325-350SAC-R-SET Images
When it comes to extracting maximum power from your 2004.5–2007 5.9L Cummins, precision and efficiency are just as critical as raw fuel volume. The S&S Diesel 325-350SAC-R-SET 350% Over Remanufactured Injectors are engineered to bridge the gap between extreme performance and mechanical longevity. By utilizing heavy-duty SAC nozzles instead of standard factory alternatives, these injectors are inherently designed to withstand increased thermal stress and combat the nozzle-seat erosion common in high-output applications. S&S Diesel applies a proprietary nozzle honing process that guarantees perfectly clean and consistent spray holes, ensuring optimal fuel atomization for a more complete burn and minimized smoke.
- Unmatched Nozzle Precision: Each nozzle is flow-matched to a strict 1% variance per set using strict original equipment (OE) standards. Testing is performed under industry-standard Viscor SAE-J967 fluid conditions at 40°C and 100 bar of pressure.
- Rigorous Injector Bench Testing: The complete injector assemblies are flow-matched to a tight 3% variance across the entire set. Testing evaluates 4 different pressure/energizing points per injector using Viscor SAE-J967 fluid at 40°C.
- Aligned Injection Profiles: The critical "rate shape" (injection profile) is precisely aligned across all units, ensuring your engine runs smoothly and predictably under heavy load.
- Custom-Matched Calibration: S&S Diesel custom-matches the injector build specifications directly to the specific nozzle flow rate for every individual size, optimizing response time and delivery.
- Internal Body Modifications: Because these massive 350% over injectors exceed the 250% (3,700 cc/min) threshold, they feature specialized internal body modifications. While increased nozzle flow inherently slows down the opening and closing times of a standard injector, these custom body modifications correct that lag, drastically improving the overall injection rate shape.
Ultimately, these remanufactured injectors represent a sophisticated calibration process rather than just a simple nozzle upgrade. By modifying the internal body architecture, S&S Diesel successfully counteracts the hydraulic delays naturally caused by massive nozzle flow rates. This meticulous attention to detail ensures that your high-power 5.9L Cummins benefits from crisp throttle response, balanced cylinder contributions, and an optimized injection profile capable of supporting serious horsepower without sacrificing injection control.
