K, so I got a little bored with my single wire (per spec) O2 sensor taking just short of a couple miles to get up to temperature and begin working, then watching it cool right off again at every stoplight in the world. (headers will do both of those things to ya)
After some searching and seeking, I stumbled across the Bosch universal heated narrowband (0-.9V per L-jet and Motronic spec) sensor.
It's a 3 wire job that after hooking up the single sensor lead requires nothing more than 1 of the two remaning wires to a key controlled 12V source and the other to a convenient chassis ground.
It's got a couple feet of harness already on it, (comes with one of those goofy splice & plug thingies loose in the box), so if you tap to the existing O2 wire, you'll have plenty of slack to get it away from all the scary pinchy/burny stuff.
The other two leads can be tapped on with as long a set of wires as you like to get it somewhere easy to work or deal with.
Bosch part # on the box is 15726 and the long Bosch # is 0258005726D09
The point of all this?
The standard Bosch replacement for the S3 runs around $100-$110+ and the heated one for the S4 starts at around $120-$140 and both go up from there.
This one off the shelf at the local Advance Auto: $63, and it works darn well I might add.
