Exergy Performance LMM Injector Set 60% Over | 2007.5-2010 GM Duramax 6.6L

Are you looking for an increase in power without sacrificing drivability or reliability? Well, look no further than our 60% over fuel injectors!

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 60% over injector set is tested at multiple calibration points, balanced to +/- 1%, and shipped with a detailed calibration sheet. There are no shortcuts.

Let Exergy give you peace of mind with your injector purchase!

Tuning will be needed for acceptable EGTs and optimum drivability.

Injector seal kit included (copper gaskets and O-rings)! For injector sizing please contact us for more information. Core $150.00 each / Pending 30 day return policy.
