Exergy 17-19 Chevrolet Duramax 6.6L L5P New 200% Over Injector w/Internal Modification - Set of 8

The nozzles are enlarged using inhouse micro EDM (Electrical Discharge Machining) and abrasive flow honing technology to achieve a matched set that hydraulically flows within 1%. Each nozzle undergoes six 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 200% over injector set is tested at multiple calibration points, balanced to +/- 1%, and shipped with a detailed sheet. Injector seal kit included (copper gaskets and O-rings)!
