Andrew,

This is a timely thread.....

I need the narrow band O2 sensor for my 1982 911sc lambda with SSI installed. 0 258 986 502 is not available in the US.

Is there a cross reference sensor you can recommend that is available in the US?

(I could never get the single wire O2 sensor to work in my SSI set up.)

Thanks.

Dave
