911SC broken oxygen sensor
 

Hello to all. 1983 SC with a 1980 engine and computer.
I found this broken/cracked sensor the other day but have not clearly identified what it is and as a result I have not been able to locate a replacement part.
In Bentley's Manual ( 240-7 ) it just refers to it as "an oxygen sensor".
My problem is I can't locate this part; oxygen sensor searches only bring up the one in the exhaust.
I am confident the brilliant minds on this forum will know the answer.
Thanks in advance -
