These are new S&S Diesel Motorsport 5.9L Cummins common rail injectors that are engineered to get the most out of your Cummins diesel. From the injector body to the nozzle, this injector was designed for maximum performance. The nozzle spray pattern and angle have been optimized to outperform a stock honed nozzle with the same flow rate, and the injector body material has been upgraded to improve reliability over the OE injector. These are the highest quality and the best performing injectors on the market.
