Exergy Performance LLY Injector Set 200% Over | 2004.5-2005 GM Duramax 6.6L

So, you've made some power but now you want more? Do you still want good drivability while running more competitive events? Well, look no further than our 200% over fuel injectors!

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. There are no shortcuts.

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

Custom tuning will be needed to take full advantage of these injectors.

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.
