Quick question, I have a 2005 s2000 and in need of buying a replacement o2 sensor. I notice 00-03; 04-05; and 06-08 s2000 have different part numbers whether it is by NGK or Denso. There is also a price difference between them. Has anyone say used a 06 o2 sensor on a 05?

 

You need an 04-05 o2 sensor.

00-03 are different.

06-09 are very different (these are air/fuel ratio sensors, not o2 sensors)
