Review on 💪 Injector Pressure Regulator Valve for Powerstroke 6.0L Diesel - Compatible with Ford Trucks E-350, Excursion, F-250, F-350 Super Duty - Replaces OEM 5C3Z9C968CA, CM-5126, AP63417 by Brandon Rogers

These are manufactured by AA Ignition. Bought 2 and all failed. It started, but not as it should. They caused an electrical malfunction. It took me a nightmare of time to diagnose and eventually bought a GP Sorensen from my local parts store to have the truck repaired. The code I finally got after launch, despite problems on both IPRs, was P2552. Somehow the solenoid shorted to ground internally and the truck acted like all the injectors were leaking. What I first thought was that the FICM is bad or I didn't fully connect it. Even after switching to a GP Sorensen IPR, the truck ran perfectly. I have tried emailing AA Ignition as per the docs in the parts box and they have not responded.
