Are universal O2 sensors ok to use? I'm not worried about the extra wiring work involved when using a Bosch universal O2 sensor, I just wanna know that it's not gonna cause problems with the pcm or fuel trim system.

In my experience they were a little long and hard to install without damaging them, I ended up going o.e.m.
I never got the universal to work correctly

If by universal, you mean one where you splice wires from old one to new one, then I have to say that in my experience I have never had one last very long. Going after market is good, if no wires need to be spliced.

I only use Denso 02 sensors, my front one is Denso and I need to buy the rear sensor as I bent the part were the wires come out so I have a code, might as well get Denso for that too.

The old one wire sensors were fine, but the multi-wire universals have a poor reputation for reliability. Have one that has just failed in my mothers Camry after only about 2 years. Worked great until about a month ago then fuel economy went to hell and it popped a CEL codes p1130 and p0171. Scanner showed STFT at +24%, LTFT at +44.5%. (Pig rich)

You can get Denso or NTK exact fit on rockauto.com for about $50.
