Motorcraft IPR Injection Pressure Regulator Valve for 2005-2010 Ford 6.0L CM5126

Motorcraft IPR Injection Pressure Regulator Valve for 2005-2010 Ford 6.0L CM5126

The CM5126 injection pressure regulator valve is a replacement IPR valve for 2005-2010 Ford 6.0L Power Stroke diesel engines, controlling fuel rail pressure by regulating the oil-driven injector system.

Overview

This Motorcraft IPR valve for 2005-2010 Ford 6.0L diesel trucks replaces the injection pressure regulator that manages high-pressure oil flow to the injectors. The CM5126 IPR valve is intended for owners and technicians chasing rough idle, hard starts, or no-start conditions tied to a failing regulator. Installed on the 6.0L Power Stroke, the valve keeps injection pressure within range so the engine runs cleanly under load and at idle.

Built For Performance

• CM5126 reference number identifies the high-pressure oil side injection pressure regulator
• Regulates oil pressure sent to the injectors so fuel delivery stays consistent
• Direct-fit replacement for the factory IPR valve location on the 6.0L engine
• Motorcraft-spec internal tolerances for stable pressure control across the rpm range
• Solvent-resistant seals suited to hot oil and continuous duty cycles

Good To Know

Q: What symptoms point to a bad IPR valve? A: Rough idle, hard starts, low power, and IPR-related diagnostic codes are the usual signs on a 6.0L. A scan tool reading live oil pressure data helps confirm the valve before replacement.

Q: Does this include the screen or seals? A: Confirm what is included in the box with the seller listing before ordering. Many installs also call for fresh o-rings and a screen cleaning as part of the job.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
