2007.5-2010 LMM Duramax New Exergy Fuel Injectors 500% Over w/Internal Modification (Set of 8)

So, you're ready to push the limit of your build and want to find an injector you can trust to take you to the podium? With our background in OE development, manufacturing and pioneers of the performance common rail fuel systems, you can trust us to fuel your passion!

At 500% over stock, these are an excellent upgrade for anyone looking to compete at the highest level. 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 500% over injector set is tested at multiple calibration points, balanced to +/- 1%, and shipped with a detailed sheet. There are no shortcuts.

An internal modification is required for all Bosch solenoid injectors above 250% over in order to maintain our target rate shape. This process will effect points across the injector's operating range, especially at idle and pilot conditions. This makes custom tuning even more important.

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

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