OEM-specification fuel injector manufactured by Delphi, OEM part number 25377440, corresponding to CFMoto part number 0800-171000. This injector features a 4-hole nozzle design and is precisely controlled by the ECU to inject atomized fuel into the engine cylinders at the exact moment, making it a critical component for efficient combustion and optimal power output.

📋 Product Overview

This product is an OEM-specification fuel injector for CFMoto vehicles, manufactured by the globally renowned brand Delphi. The Delphi part number is 25377440, corresponding to the CFMoto original part number 0800-171000. This injector is the core actuator of the electronic fuel injection system. One end mounts into the fuel injector seat, and the other attaches to the injector cap, which connects to the fuel line. The Engine Control Unit (ECU) precisely controls the injector's opening timing and duration, delivering fuel in an optimally atomized state into the intake manifold or cylinder to mix with air for combustion. This injector features a 4-hole nozzle design, enabling finer fuel atomization, improving combustion efficiency, optimizing power output, and reducing fuel consumption and emissions.

🔧 Important Installation Notes

Manual Installation: Always install the fuel injector by hand, pushing it into the seat. Never use a hammer or tools to strike the injector, as this can damage internal precision components.
O-Ring Replacement: When removing and installing the injector, the O-rings on both ends must be replaced with new ones to ensure proper sealing and prevent fuel leaks or vacuum leaks.
Do Not Rotate: After the joint between the injector and the injector cap is installed, do not rotate the injector, as this may compromise the seal or stress the fuel line.
Pressure Relief: Before removing the injector, perform fuel system pressure relief if necessary to prevent injury from high-pressure fuel spray.
Leak Test: After installation, always perform a fuel system leak test to ensure all connections are sealed before starting the engine.
