Oxygen Sensor

[hgray14]

I saw this in a previous and now closed thread:

"The #15097 (direct fit) is $130-$150 from the usual favorite sources; the universal #15738 are about $85 from a bunch of places."

I am seeing a universal Bosch on ebay for $27...that is a huge savings if all I have to deal with is a bit of wire splicing. What do you think? Should I be suspicious that they list the same O2 sensor for both the front and rear? What is the actual difference? ...different threading, different length, different wires???

I sent them a question asking for the part numbers and how the front and rear can be the same.

thanks for your input
