Overview

The GM Genuine Parts fuel injector is an electro-magnetic valve that meters fuel into the engine's intake manifold or cylinders for combustion. It is a GM-recommended replacement for your vehicle's original component. The engine management computer operates the injector by applying an electric current to the injector solenoid winding, which opens the needle valve and allows pressurized fuel to be atomized into the intake airstream. These original equipment fuel injectors are manufactured to fit GM vehicles, providing the same performance, durability, and service life expected from General Motors.
