2000 Mercury Sable O2 sensor
Should be the same if the engine is the same as those 2 vehicles were almost twins. To be sure look up both parts at www.tascaparts.com and compare the part numbers.
Absolutely , exactly the same part and part number , Former FOMOco dealer service employee . Caution use only the FORD part . Generics maybe cheaper but can cause false engine malfn indicator illumination (MIL)
I agree with using Genuine Ford parts on this repair.
