I went and ordered a Bosch O2 sensor (after cats) from Napa today. Both clerks swore the correct part #15717. When I got home, I checked the website and it lists #15787. It's not in stock and I don't want to wait longer for the mistake.

Does anyone have the correct part number? Thanks.

Both are the correct part #'s. #15717 supercedes #15787 when available. You just need to make sure the wiring harness is the long one for the rear sensors.

How much are they charging? The Ford/Bosch sensor is exactly the same except it has Ford and Bosch stamped on it. I ask because when I replaced mine I checked an auto parts store and they wanted $89.00. Then I called one Ford dealer and they offered them at list for $89.00. Then I called another dealer and they offered them at $63.00 each under the preferred customer program to get me to buy the parts from Ford.

 

Thanks for the help. I paid $57.00 for each (company discount) and got the long wiring harness. I should have gotten it two weeks ago when Bosch had a nationwide sale for $49.00 each!!
