New Genuine Nissan BNR32 GTR RB26DETT Rear Oxygen Sensor or O2 Sensor. If your oxygen sensor is more than 15 years old, or over 96,000 kilometers, its time to change it. When worn out, these sensors can no longer properly relay O2 data in your GTR’s exhaust back to the PCM to make the proper adjustments. This is not a cheap reproduction, but the correct unit calibrated especially for the RB26 motor with the right connector.
