which o2 sensor to get?

[rathrbcruisin]

I picked up a 98 explorer 5.0 and the engine light is on. it has code p0133 which it says bank 1 sensor 1. Is this the one i need to remove the console to get at? what part is this? i have found bosch at advanced auto but they have like 3 different part numbers, and they all fit!? I'll be bringing this home this weekend so i want to go ahead and get this done as soon as possible. Thanks!

That would be passengers side up by the exhaust manifold (upstream). Rock auto lists it for the Bosch sensor #15717 @ $25.79. When I replaced a bad O2 sensor in my 00 Ranger the original sensor was a Bosch.

I think the only difference is the length of the wire, which is apparently a factor in its performance. Take the old one in and match it up.
