I'm looking for a good source (Bosch quality at lowest cost) for pre-cat and post-cat O2 sensors for the 997.2 9A1 engine?
The OEM part numbers would be:
9A1 606 128 00 - pre
9A1 606 138 01 - post
thx
Bill

I would recommend Genuine Porsche Bosch O2's.. Sonnen has a "great" price. Call Neil, Ryan, Gina or Greg.. 866. SONNEN1

I think that you will be OK with just replacing the preCAT O2's and leaving your old rear O2's.. Unless you have over 100K on them.

Thanks Kevin!

www.rmeuropean.com has the pre for $102 and the post for $56 in Bosch OEM, free shipping. They have always done a great job on parts I've ordered from them.

Excellent!! Thanks for the response and source info. I don't think I have seen this supplier name before but have added then to my parts bookmarks.
I have also found the pre-cat sensors at Warehouse33 and Partsgeek for less than $110 and advertised as Bosch 9A1 606 128 00.
