Ford didn't stop using the same plug because the crux of the problem is not the plug but the head.

 

The crux is THAT plug (2 piece) in That head. When a 1 piece plug is used in the same head, the problem seems to go away.

 

Not really. Ford could've much more easily switched to a one piece plug instead of re-designing the head. They chose the head instead. Therefore the plug is by far the lesser of the two issues.

Isn't this fun, going back and forth like this?

 

Here's the answer to your broken spark plug. $70.00 and do it yourself fix.
