Ok i well i want to buy the 2 front ac delco o2 sensors before the cats for a 01 ta what are the parts numbers because on this one parts site it says postion 1 and 2 and 3 stuff like that. so i just wanted to know so i dont order the wrong one.

 

Also does any one else know where i can buy them at not looking for the cheapest price just a fair price not some dealer 150 for just one lol

 

Search function I just did found all kinds of O2 info, ...
But look at oxygensensors.com & you can find them for $47 each. Plus it tells ya the Walker or Denso number for comparison.
There was a thread that I had seen that had the Bosch & GM/Delco mubers listed also, ..., Back in a minute if I can find it again, ...

 

Here, this might help if ya check back in time, ...

I have 2, the only differences are the length as far as i know they will work on either bank. One is maybe 2 inches longer then the other side. Let me know if you are interested.

 

yea im not really trying to buy used sensors
