2003-2004 5.9L Cummins Exergy New 100% Injectors

Do you want to edge out that Mustang at the track or put another 5' on the next truck? Are you looking for an increase in power without sacrificing drivability or reliability? Well, look no further than Exergy's 100% over fuel injectors!

The original VCO nozzles are replaced with higher flowing SAC type to enhance the rate of injection at flows that are double that of a stock injector. The nozzle is then enlarged using abrasive flow honing technology and are hydraulically flow matched to less than 1%. Each nozzle undergoes four separate quality control checks throughout the process before being installed back onto the injector. All components are built and tested on specialized equipment designed and built in-house at Exergy. Every 100% over injector set is tested at multiple calibration points, balanced to +/- 1%, and shipped with a detailed calibration sheet. There are no shortcuts.

Tuning will be needed for acceptable EGTs and optimum drivability.

Core Return: Exergy requires that all cores be returned within 30 days from original purchase of product. If you fail to return the core(s) within 30 days, you will be charged in full for the core(s) ($150 per injector). Cores that have missing and/or damaged component(s) will not receive credit.
