Exergy Performance Reman Injector Set 30% Over Stock 2003-2004 5.9 Cummins
Exergy Engineering is well known for its high standards and precise quality control when it comes to building common-rail injectors. This is why we only offer Exergy performance units for common-rail diesels, be it for Duramax, Cummins, or Power Stroke engines. These remanufactured performance injectors are based on factory Bosch units found in the ’03-’04 common-rail 5.9L Cummins, but are modified internally and equipped with the nozzle of your choice.
Modified nozzles are only available for complete injectors (not sold separately). Every customer’s used set of injectors receives baseline testing upon arrival, where it is determined whether or not they are suitable candidates for the requested modifications.
All of Exergy’s injectors are flow-tested to ensure the nozzles are balanced to within 1% across the entire set. Injectors are also tested across their full operating range. With the absolute best test equipment available, Exergy brings more high performance fuel system know-how to market than any other company. It’s a name we trust more than any other in the diesel industry when it comes to injectors, nozzles, and pumps.
