6.0 Powerstroke IPR Valve – Grizzly GA33417

Restore reliable starting, smooth idle, and consistent power to your 2005–2007 Ford 6.0L Powerstroke with the Grizzly GA33417 Injection Pressure Regulator (IPR) Valve.

The IPR valve is a critical component of the high-pressure oil system (HPOS) that actuates the HEUI injectors. It regulates oil pressure from the high-pressure oil pump so the injectors receive the precise hydraulic force needed for proper fuel delivery, atomization, and combustion. When the factory IPR fails, sticks, or leaks, it commonly causes hard starts (especially when hot), no-start conditions, rough idle, surging, stalling, and loss of power.

The Grizzly GA33417 is a direct-fit replacement engineered to meet or exceed OEM specifications for accurate pressure control and long-term durability in the demanding 6.0L Powerstroke environment.

Key Features:

• Precision-engineered direct replacement for 2005–2007 6.0L Powerstroke
