ACDelco Gold (Professional) Oxygen (O2) Sensors are the high quality alternative to Original Equipment (OE) parts. These sensors are special feedback sensors on your vehicle's exhaust system. They measure the proportion of oxygen in exhaust gases. Using this measurement, the engine control module can adjust the air/fuel ratio to the optimal value. At this ratio, engine performance, emissions, and fuel economy are all optimized. ACDelco Gold (Professional) parts are manufactured to meet your expectations for fit, form, and function, making them a smart choice for General Motors vehicles, as well as most makes and models, including special applications. These high-quality parts are backed by General Motors. Some ACDelco Gold parts may have formerly appeared as ACDelco Professional. ?
