I did, and thought there was a lot to be desired in his testing.

If you put enough metal on the end of your plug it will raise your compression for better performance.:D
I had a dual overhead cam hemi design head Fiat Spyder a long time ago around when those Iridium plugs came out.

Sure, maybe the electrode might last longer if it ran, but that motor wouldn't even start with those in it, just pop spit and sputter.
Put the used NGK's back and it ran perfect again.
