It is a $2 spark plug, I am over it. I just can't figure out if it was manufacturing error or my error. I guess time will tell.

That is what I am thinking. My AFR's have gone berserk this week for some odd reason and I can't figure it out, so I assume I was running a little lean and the heat caused it to crack. I'll check them after I dyno on Saturday and see if it happens again.
