ACDelco GM Original Equipment Remanufactured Fuel Injectors are GM-recommended replacements for your vehicle's original components. They are electro-magnetic valves that meter fuel into the engine's intake manifold or cylinders for combustion. The engine control module (ECM) operates the injectors by applying an electric current to the injector solenoid winding - this causes the needle valve to open, allowing pressurized fuel to be atomized into the intake airstream. Remanufacturing the fuel injector is an industry standard practice that involves disassembly of existing units, and replacing components that are most prone to wear with new components. Damaged and obsolete parts are replaced and completed units are tested to help ensure they perform to ACDelco specifications. In addition, remanufacturing returns components back into service rather than processing as scrap or simply disposing of them. These fuel injectors will provide the same performance, durability, and service life you expect from ACDelco.
