These are 100% NEW Fleece Performance 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.
New Engineered Nozzle Options
Available in 50 or 100 HP options, the engineered nozzles are brand new units manufactured with the highest of quality & control standards to their specified size. These are not simply stock nozzles that have been media honed! Specifically designed with a modified spray pattern and manufactured to size, these nozzles are engineered for better fuel atomization which leads to improved in-cylinder flame propagation. What does that mean? That means you will not have to rely on as much injector duration and timing to achieve your desired horsepower goal, which leads to better engine health, longevity, fuel mileage gains, and enhanced driving characteristics. Using the latest in SAC type injector nozzles, not only are they of higher quality, but you can expect better longevity compared to the factory VCO style nozzle.
Custom Flowed & Balanced Injector Services
Handled by the best in the business when it comes down to Common Rail Injector Performance, Fleece Performance proudly uses Exergy Engineering for all custom injector needs. Done with exacting quality & control, Exergy processes injectors in a manner that will not only improve the engines performance but enhance the tuners ability to calibrate and control them in every application.
Combining New Engineered Nozzles with Custom Injector Services
Both the 50 and 100 HP nozzles can be used as a base nozzle to build off of in a Custom Flowed & Balanced Injector application. The 50 HP nozzle is respectively equivalent to a 25-30% over stock nozzle, the 100HP 45-50% over stock. When a target rating of 100% over stock is desired, and a 100 HP nozzle is used, then only a 50-60% over media hone process is required.
Attention to Detail
03-04 Model years were equipped with a different piston bowl and corresponding injector spray angle than 06-07 models. Fleece Performance has insured that the correct spray angle is used for each style piston bowl for optimal performance!
