O2 Sensors

BMW oxygen sensors (or "O2 sensors") send real-time information to your BMW's ECU to control the proper air-fuel ratio. BMW O2 sensors are needed for optimal performance and efficiency in all driving conditions. The condition of your oxygen sensors should never be ignored. Failing O2 sensors will trigger your BMW's check engine light, put your BMW into a lean or rich running state. This can affect gas mileage and even cause engine or cat damage. O2 sensor replacement is straight forward and cheap insurance. Use our SEARCH BY MODEL feature to filter these items for your BMW.
