Bosch Oxygen Sensor P/N:18188
Bosch 15088 left oxygen sensor for the 2001-2006 BMW M3 6-cylinder 3.2L and other vehicles measures oxygen in the exhaust and sends air-fuel-ratio readings to the ECU. This Bosch O2 sensor is a heated narrow-band unit that supports closed-loop fuel control.
A check engine light, rough running or poor fuel economy can mean the oxygen sensor is worn, though a dirty mass airflow sensor or a worn spark plug can be behind them as well, so find the cause first. This listing is a single sensor for the upstream left position, and the fitment calls for one.
It is listed for a wide range of BMW and Mercedes-Benz models, including the 2001-2006 BMW M3 6-cylinder 3.2L, the 1996-2002 Mercedes-Benz SL500 V8 5.0L and the 2001-2002 BMW Z3 6-cylinder 3.2L. For any other car, go to the "Vehicles it fits" section and look up its year and engine.
