Which Oxy Sensor do I need to replace.

[Gelbster]

Some experts (I am not an expert) suggest replacing all 4 O2 sensors with the same brand at the same time. Make sure you don't buy the O2 sensors intended for the older Boxster - different connector.Bosch seem to be the most popular brand.I would give you a link to the correct items on the Pelican Parts site but their link is not working for me.

At $200 plus a sensor, I am trying to see if I can get away with finding the bad sensor only... If that doesn't work I may have to do that.

You can fins the sensors way cheaper if you get the bosch part number. As i recall, all the sensors use the same bosch part on this car
