Motorcraft CM5109 is a direct-replacement fuel injector for 2003 and 2004 Ford Ranger trucks equipped with the 4.0 L SOHC V6 gas engine. It helps restore proper fuel delivery when an injector is sticking, leaking, or misfiring, using OEM design and calibration to support factory-style spray pattern and atomization.

Motorcraft CM5109 Fuel Injector Features:

• Designed for Ranger 4.0 L SOHC V6 fuel injection systems, including Edge, Tremor, XL, and XLT trims from the supported model years.
• Direct-fit OEM replacement design supports a clean installation in the original injector location without custom fuel system changes.
• Calibrated fuel delivery helps the engine maintain smooth idle, consistent throttle response, and dependable combustion when replacing a failed injector.
• When one injector fails on a high-mileage engine, inspecting the remaining injectors or replacing the full set can help maintain balanced fuel delivery across all cylinders.
