What motor?
I'm getting ready to do the upstream O2s {CEL & code}on my '98 4.0. Anyone already have the PNs?
Going by Rock Auto's web site the part # for Bosch O2 sensors in your 98 are, upstream left - 15716, upstream right - 15717, & downstream - 15719. When I replaced the upstream l/s O2 sensor in my 2000 the original sensor was Bosch so I replaced it with the same one.
