YES....all of the "sensors" themselves are identical. The part numbers are different ONLY because of different wire lengths.

Any sensor will work in any position.

Well not really, like he said the actual sensor is the same but the connections can vary. You need to get the correct part# for whatever car you have.

.......if we're talking LS1 engines.......factory exhaust ports........97-02 LSx......they are identical in every way.

I'll make it easy....measure how much length you need for whatever position you need a new sensor for......if 16" is long enough, including tucking it behind heat shields and/or keeping the wire away from anything hot, etc.....buy Denso #2344025. Done.

If you need more wire length, Bosch is an option, or wire extensions. I would go with extensions and use the Densos personally.

I used the vette o2s for my headers. The leads are really long. All I do is zip tie or wrap them up out of the way. They are fine.

fwiw i just bought 2 new sensors from rockauto,
denso 2344087 upstream right, denso 2344025 upstream left.
I forget which side had the longer wire length, but they replaced what was stock in terms of wire length exactly.
