Genuine Mazda Rear Oxygen Sensor for RX-8

This is a genuine Mazda rear O2 sensor (found installed in your catalytic converter) for your RX-8 in many cases installing a pattern sensor will mean that cat monitoring (whitch is primarily what your rear O2 sensor is for) will not work correctly, we have found in the past that customer who have ionstalled a cheaper pattern or universal rear O2 sensor have had a failed cat however the ECU has failed to detect this.

This is the sensor that is installed in the catalytic converter.

Please note that there are 3 different sensors depending on your vehicle. Please select your correct part from the drop down menu.
