i find this all hard to beleive so if a dealer breaks a spark plug on your car and its still under waranty do you have to pay extra ----have they changed the desighn--i would of thought ford would of done some testing on these plugs before they used them on there engines----has anyone made a spark plug to fix the issue---sounds crazy from a place like USA you would think it would of been in the courts and fixxed fast
