O2 sensors

[nordictom]

Does anyone know the MotorCraft part numbers for the O2 sensors for a 1998 Explorer 4.0 SOHC???

Another question......... does the drivers side O2 sensor have a longer pig tail?


Thanks,

which ones do you need? if you go on rock auto's site, they tell you the part numbers. also, if you didnt know, bank one is the side of your #1 firing cylinder, up stream is the first o2 sensor before the first cat, and down steam is after the first cat. it took me 4 years to figure that out, lol

Thanks for the info.

Ford Dealer parts dept told me the part #'s, the downstream are the same, the upstream are different #'s. The Passenger side has a short pig tail (MC# DY831)& the drivers side (MC# DY862) has the long pigtail.


Thanks,
