So...I tried a spark plug in the hole and it was too small.  Does anyone
know the size/thread pattern for the O2 sensor? I�d like to go buy a plug
for it and don�t want to keep running in and out of the store trying
different plugs if I don�t have to.

Ron, maybe a note on the cat's product description about tightening the
plug would help less experienced folks like me avoid this problem.

Thanks again,
Brian
