yes, 2 and 2...if your not getting any codes, they are OK.
If they go bad, you'll still be able to drive the car so its up to you when or if you want to replace them. Maybe purchase and replace the pre cat ones now and do the others later if your worried.

I got the $20 VW sensors that work on some of the a4s but not on mine
or yours. Then I purchased the universal O2s (some kind of chrysler sensor) that work or people claim to work on our cars. They needed to be clipped and the old connectors soldered on. They worked fine on mine for a few months then I started to get CELs and codes. I'm not sure if it's something else that is causing them to have problems or not.
I'd either wait for them to go bad or replace them with OEM if I were you. From my understanding, the front pre-cat sensors are the important ones.
