The 5-wire wide-band oxygen sensor is a replacement sensor for 2017-2020 BMW M760Li xDrive and 2017-2019 BMW M760i xDrive with the 6.6L V12 engine in the upstream position. It measures the exhaust air-fuel ratio across a broad range so the engine computer can meter fuel precisely. A built-in heater brings the element to operating temperature quickly after a cold start.
