2001-2004 LB7 Duramax Reman Exergy SAC Injectors 100%

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 factory nozzles are swapped with a SAC type nozzle with the same spray pattern as factory. Though the latest factory nozzle with the DLC coated needle has a far superior reliability track record than its predecessor, historically the SAC type nozzle has also proven to be a dependable option. The nozzles are 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.
