Hmm Max i think that link you gave includes too many options and not all of them are correct. I'd say the best choice is NGK IFR5J-11 or cheaper NGK BKR6E-11 or DENSO K20PRU-11.
Looks like I have some wrenching to do this weekend!
I also decided I'm gonna go ahead and check out the stat and see if it needs replacing or not. My guess is the stat probably is stuck open or maybe something wrong with the gasket for it.
Well, could only change four of the plugs since the sway bar was covering the middle spark plugs... drrove it for a bit, and code P0301 came back, and when I get home from driving, I re-scanned again and now P0171 is pending.
Get the other 2 plugs changed out and then you need to find out if you still have a misfire being picked up. Drive a bit more. If so you can get that because when you have a misfire you have not burned all the fuel therefore you did not consume all the O2 so your O2 sensor will indicate lean. You can use a bit of carb cleaner and check for intake leaks as well as this would cause un-metered air going to the engine.
Normally you would find either intake gaskets leaking, Sparkplugs (Coil possible here too), or failing O2 sensor.
I DO agree that it's too many choices to pour through and decide on.
