My 02 sensor just went about 2 months ago and I have 28K miles on my 08 s2000. It was still under warranty, Honda replaced that and the cat since they said that was bad to. My car was completely stock during that time

This is a direct plug in replacement from a very reputable manufacturer. This is for an 03.

You could have just looked at my post a couple above....

Good link, but that is for the secondary post cat sensor, I need the Pre cat sensor.

I found a good upstream Denso o2 sensor P/N 234-4124

AP2 first sensor is different fron the AP1's and more expensive.

I would say this is normal and would happen without any particular reason other than regular wear.
See my post here:

There is actually a TSB for '06+ and they have a new design for the o2 sensor.

Yes, you can replace it easily yourself if you've ever done an oil change. It's similar.

No difference between AP1 and AP2, but a difference between 00-05 and 06-09. Latter years are almost double, but still way less than OE at about $120.

04-05 s2k has different sensors than 00-03.

I lost the rear O2 in my 2005 @ 61,000 miles due to the converter shifting internally and snapping the tip of the sensor clean off, it seems like more of a common thing that is going on later in life with these cars. Be sure your converter is in good condition and the first "puck" hasn't shifted or you'll just break the other sensor that was just put in and the CEL will come back on.
