Can't find the number anywhere. Is it 4, or 8?
Yes, four total.
Two O2 sensors for mixture control, one for each bank.
Two O2 monitors to verify that the catalytic converters are working correctly, again one for each bank.
I'm looking at RockAuto. How do I find out which parts I need? Is it any 2 x upstream and any 2 x downstream?
You can also try www.sparkplugs.com. They tend to be a little cheaper.
Wow man, not even close. That site is almost double the price of RockAuto.
RockAuto NTK 2 x 22060 and 2 x 22500 = total $119 with shipping.
Same items on that website = total $188 with shipping.
%50 =/= almost double, but it looks like SparkPlugs prices have gone up substantially. As mentioned, grab a 5% code to save more on RockAuto. Also, is there a specific reason you are wanting to swap the downstream sensors? They almost never cause any issues and there is nothing to improve by replacing them.
Really? I recently bought 4. Luckily havent put them in yet. Around 140k on my originals. You dont think theres a need to replace the downstream ones? I have a long history (past 40k or so) of bad coils, and misfires.
Thanks for the info...what would be sign of failure for the downstreams?

Not what you asked, but when my upstreams went, my CEL was preceded by awful fuel economy.

this may actually be good news for me. I got a P0420. Cleared. Then P0420 and P0430 together. Cleared. Haven't come back in a few thousand miles, but gas mileage has been poop since then.
It looks like there is still plenty of anti-seize on the threads. I would just wipe it off the rest of the sensor and install it. They should come with a plastic cap on the end of the sensor to prevent that from happening.I already have a pretty good idea about what to do, thanks to the help from a member, but I just wanted to be completely sure.
Anybody know what this black crap is? looks like it was meant to be on the threads, but with the way it was packaged its all over...
