Premium remanufactured Bosch High Output fuel injector set (6 injectors) for Dodge Ram 2500 and 3500 trucks equipped with the Cummins 6.7L High Output (H.O.) diesel engine.
Each injector in the set is professionally remanufactured using OEM Bosch components, ultrasonically cleaned, precision calibrated, and flow tested to meet original equipment specifications. Every injector undergoes extensive quality control testing before shipment to ensure balanced fuel delivery, smooth engine operation, and maximum performance.
This High Output injector set is engineered to:
- Restore precise fuel atomization
- Improve horsepower and throttle response
- Reduce excessive smoke and rough idle conditions
- Eliminate injector balance and fueling issues
- Support consistent fuel flow across all six cylinders
- Maintain High Output engine performance standards
Replacing all six injectors as a matched set helps maintain proper cylinder balance, smoother engine operation, improved fuel economy, and dependable long-term reliability. A complete injector replacement is often recommended when servicing high-mileage or heavily worked Cummins engines.
Designed specifically for high-pressure common rail fuel systems, this injector set delivers the fuel flow and precision required by Cummins High Output applications while maintaining OEM spray pattern and performance characteristics.
This set replaces OEM Bosch injector part number 0445124039 and compatible Cummins references. Fitment is verified before shipment.
