O2 Oxygen Sensors - 2003 Trac

[David Schmidt 2]

I'm getting close to 100K and want to replace the Oxygen Sensors. At least the top ones. The two after the CAT are not as important. I like to use RockAuto but the list is huge. Does anyone know what the factory part numbers are for the oxygen sensors? I have a 2003 Sport Track.



thanks - Excalibur

well..got no help..think I got the right stuff though.



Upstream or Pre Cat should be Qty. 2 Bosch 13117



Downstream or Post Cat should be Qty. 2 Bosch 15716.



I went with the Bosch as recommended. Each float around $35 bucks or so. Motorcraft OEM is like $60 - much more. I ordered from A****zon dot com. They had a cool Oxygen sensor removal tool kit for $17 dollars or so - several sizes in a plastic red too box. Good deal. I picked up a thread chaser for a few dollars also - for just in case. I got the Upstream ones as they really affect the ride quality I'm told - down stream just checks for whats left over. I hope they are not hard to get out.

Bosch work fine as above.
