Does anyone here know the part numbers and prices for the O2 sensors. I'm assuming the important ones are pre-cat?

The part number for the downstream (after-cat) is 9A1-606-198-01 at ~$180.
The upstream (pre-cat) is 9A1-606-188-01 - I don't know the price of these. And yes, these are more important the downstream, although both are important. The downstream sensors in this car are not easily tricked ha!!

You're awesome! Would you happen to know the Bosch equivalent part number? I usually buy the Bosch part to save on the Porsche tax. Either way, $200 each at Gaudin Porsche so that saves me $100 each from my local Hawaii dealer.

Bosch part # I am not sure about, but just did a quick search and maybe it is this one?
