"ACDelco GM Original Equipment Fuel Injectors are designed, engineered, and tested to rigorous standards, and are backed by General Motors. When your vehicle struggles with rough idling, engine hesitation, or poor gas mileage, a clogged or leaking nozzle is often the culprit disrupting the combustion process. These electro-magnetic valves work directly with the engine computer to meter and spray a precise, atomized mist of pressurized gas into the intake airstream or cylinders. By controlling the exact amount of fuel delivered based on pulse width, they restore smooth acceleration, ensure reliable cold weather starts, and prevent misfires during demanding stop-and-go city driving or heavy towing. Engineered to withstand high under-hood temperatures and maintain proper pressure within the fuel rail, this component is rigorously validated to support clean emissions and deliver consistent power mile after mile."
