My friend just callled me back and "splained" this to me.
He said, what he gave me was 2 spark plug anti foulers.
They are 18MM
So basically you get the 2 anti foulers, screw one into the down stream (after the cat) O2 hole. Drill the second one out to 1/2" and screw it into the first one, then screw your O2 sensor into them. This gives the internal depth you need for the O2 sensor, He said use antisieze on them.
What this does is takes the O2 out of the stream of exhaust and fools it into thinking the air is cleaner after the cat.
He also said if you do this to the upstream O2 it will think its running lean and richen up the mix so dont do that!
