Should I replace my O2 sensors?

[Jeff7]

Well I'm going on course for about 4 months, so I guess I don't need to decide until I get back haha. If I do replace them what brand do you guys recommend? I was looking at OEM replacements or Bosch, any opinions on that or other suggestions?

I went with OEM.

Stick with OEM for sure. Personally though, I say don't fix it if it ain't broke. My '97 Suburban is still running factory O2 sensors with zero issues. The only reason I replaced them on my red truck was that I replaced the entire exhaust system from headers back and it just made sense.

Unless you're getting a CEL, I'd leave them alone.

Speakin of o2 sensors, my CEL just keeps going on and off for em so idk if they're out or not, usually changes with the weather, I'll prolly just go ahead and do em when I redo exhaust

Do it with the exhaust hot. They usually come out alot easier that way.
