Do the upstream and downstream sensors have different calibrations or do they just have different connectors? Why is it important to distinguish up/down stream?

Looking for just one, let me know.

BTW did you price one at a Dealership, I bought a couple a month or two ago and was presently surprised by the price. Apparently Ford amalgamated a number of different part numbers and reduced pricing. Who knew!

Just checked online but ended up buying it from Wes and received and installed today.
