Exergy Performance 30% Over Stock Injector Set 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 performance injectors are based on brand new Bosch ’03-’04 common-rail 5.9L Cummins injectors, but are modified internally and equipped with the nozzle of your choice. They allow Exergy to start with a fresh set of injectors (vs. used cores) to begin the modification process.
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.
