This is a genuine BMW O2 / Oxygen Sensor, OEM part number 7603023, sourced from a donor vehicle. Also called an oxygen sensor, it monitors exhaust gases to adjust the air-fuel mixture. A failing sensor can trigger the check engine light and reduce fuel economy. This sensor fits select 3.0L inline-6 engines—both naturally aspirated and turbocharged—from the N52 and N55 families, as used in the 528i and X3.
