New Genuine Nissan R33 RB25DET 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 GTS25 exhaust back to the PCM to make the proper adjustments. This is not a cheap reproduction, but the correct unit calibrated especially for the RB25 motor with the right connector.
- Fits Series 3 made from 11.1997 - 11.1998
