ACDelco 213-3902 Professional Heated Oxygen Sensor

An ACDelco Professional, premium aftermarket Oxygen (O2) Sensor is the ideal high quality replacement for your GM vehicle. It is a special feedback sensor on your vehicle€s exhaust system. This sensor measures the proportion of oxygen in the exhaust gases. Using this measurement, the engine management computer can adjust the air/fuel ratio near the optimum value of 14.7:1. At this ratio, engine performance, emissions, and fuel economy are all optimized. This premium aftermarket replacement oxygen sensor is manufactured to meet or exceed your expectations for fit, form, and function.
