When to replace O2 sensors?
At what mileage should you replace O2 sensors, or should you only replace them when O2 error codes appear? I also heard that it is typical for the for O2 sensor performace to degrade without resulting in a trouble code and increases in fuel economy can be had with new ones; is this true?
My car currenly has 105 XXX miles on it.

I don't know if it's performance will degrade without throwing a code, but I always assumed you should wait until it did throw a code. As far as a specific mileage I don't know. However, if you have 105K+ miles w/original O2's it would probably help.

Does anyone else have any more opinions or first hand experiences?

With 105k miles, I'd definitely throw some new ones in. You can get both of them for ~$70 from Autozone. Also, don't mess around with Bosch O2's (learned that one the hard way a while back), stick with AC Delco's. If Autozone is out of them, give Jason Cromer a call (see my sig) and you'll get about the same price, just have to pay shipping.
