ACDelco GM Original Equipment Fuel Injectors are electro-magnetic valves that meter fuel into the engine's intake manifold or cylinders for combustion, and are GM-recommended replacements for your vehicle's original components. The engine control module (ECM) operates the injector by applying an electric current to the injector solenoid winding, causing the needle valve to open, and allowing pressurized fuel to be atomized into the intake airstream. These original equipment fuel injectors have been manufactured to fit your GM vehicle, providing the same performance, durability, and service life you expect from General Motors. ⚠ WARNING: Cancer and Reproductive Harm - https://www.P65Warnings.ca.gov
