BMW O2 / Oxygen Sensor (OEM 8604930) – a genuine used oxygen sensor removed from a donor vehicle. This sensor monitors exhaust oxygen content for the range-extender engine, helping the ECU adjust fuel mixture. A failing sensor often triggers a check engine light and can reduce fuel economy. Fits the BMW i3 and i3s equipped with the 0.6L 647CC two-cylinder BEV REX engine.
