I need to replace the o2 sensor on my 93 3.2 rodeo, what brand have you all used and like? I understand its in front of the cat right after the y-pipe correct?

Also, i need to replace my plugs and wires. From the search I have decided to go only with ngk for 2 reasons
1) I know they wont throw codes (however i think this is only on the never 3.5l but I still want to be on the safe side)
2) Where ever I order them from I can order some spares for my quad as Im in need of some backup plugs anyways..

I need to also replace the plug wires, any recommendations or part numbers?

Also, I would like to order all this stuff off the internet, what sites do you all use to order tuneup parts?

Thanks
Nate
