This is the second time this happened. First was an iridium plug in a different cylinder, the "hook" broke that time. Why???

 

Possible preignition can destroy a plug like that. Are there any signs of detonation and or preignition?

What is pre ignition? How do i detect it? Detonation has been my problem ever since because of the crappy gas available in my area.

 

well, you answered yourself. detonation is breaking your spark plugs like that.
I would do something about it unless you like buying new motors

 

what part of NC are you in?

 

pre igntion = detonation ???
