Making O2 Sensors

Today I decided to put the front clip back on the S4 finally, and I stole the radiator. Originally I had planned to use a radiator from a B6 3.0L since it would fit in the same space as my current one, but the one on the car I pulled everything else off of had a big crack on one of the end tanks. I also plugged the trans cooler ports on the B5 S4 one.
I figured I would work on my O2 sensors. One was diagnosed as bad, and I went ahead and ordered two new Bosch "universal" sensors. Basically you splice them to your factory connectors. This saves you a chuck of $$ for each sensor. It was pretty easy honestly.



Cleaned turbo inlet pipe brackets and re-mounted them. I love it when they shine. I also spoke with the gentleman that's working on my wiring harness adapter, and it should be done shortly. Then the real fun will begin.
