$200+ for one pre-cat sensor on my 2006 turbo. Anybody have a cross reference part number from one of the usuals? I am sure that NAPA only wanted $80 or so last time I asked but I want to make sure I get the same connector as the OEM supplied unit

Rear is a Bosch 16498 and front is a Bosch 17174. Both can be had for much less than $200.

I suspect that Andrea quoted for the pair rather than the one I need. My local AdvanceAuto list a Denso as direct fit at $106. Would it be a problem to just replace one with a Denso?

If its technical specs match OEM, no it would not cause a problem.

Put the Bosch sensor part #'s in an Amazon search and you will find some pretty reasonable prices, OEM manufacturer.

Does the Bosch 17174 have the same plug on the end or will I need to change it?

Thanks all. Ordered online for $75 and free shipping Vs $205 from Sunset. Apparently Porsche does not support "aftermarket" items. Lets hope it fixes my perpetual random bank2 misfire problems....

Just curious, were you getting any fault codes related to the O2 sensors? OBDII has specific fault codes for O2 sensor related faults.

Yes, curious. All of Bank 2 or just random cylinders? Coil wiring? Injector wiring? Don't want to go negative but I have seen low cylinder compression throw a cylinder misfire (probably one of the least likely situations, especially considering it's a Turbo).
