Oxygen Sensors

Check engine light on? Poor emissions coming from your engine? It may be time to replace the oxygen sensors. These sensors continually monitor the fuel/air mixture as well as the exhaust to keep your car running smoothly. Many BMWs require four sensors - one before the catalyst and one after the catalyst on each bank. Enter your model below to get started.
