ALLIANT POWER AP63416 INJECTION PRESSURE REGULATOR (IPR) VALVE

The Alliant Power AP63416 Injection Pressure Regulator (IPR) valve is designed for early-model Ford® 6.0L Power Stroke and International® VT365 diesel engines equipped with HEUI fuel injection systems.

The IPR valve controls high-pressure oil flow inside the HEUI system, helping regulate injector pressure and fuel delivery timing. A failing IPR valve can cause hard starts, rough idle, low ICP pressure, poor throttle response, injector performance problems, surging, or no-start conditions.

Built as a direct-fit replacement, the AP63416 is engineered for dependable operation in demanding diesel applications and helps restore proper high-pressure oil system performance.
