Alliant Power Injection Pressure Regulator (IPR) Valve AP63417

Replace the failed Injection Pressure Regulator (IPR) in your Ford 6.0L Powerstroke with the Alliant Injection Pressure Regulator Valve AP63417. The IPR valve is a critical part of your Powerstroke engine as it regulates the pressure of the oil coming from the High Pressure Oil Pump (HPOP) to the fuel injectors. If the IPR fails, the valve will usually bleed off more pressure than necessary, which may prevent the injectors from firing. Common symptoms of a faulty IPR can include a rough idle, injector surging, hard start or no start, and stalling.
