I know I saw a picture that someone posted a while ago. It's an adaptor for the 02 sensor to fix the cel problem. It has threads on both side, one side screw on the O2 sensor and the other side screws onto the pipe. I can't find that post now.

Anyone know where I can find that?

Thanks,
Adrian

 

I think you mean the spark plug antifouler things

 

Ah! Found it. Antifoul is the keyword!
