IIRC, SVT owners always had problems with the +4. To be honest, the Ford spark plugs aren't that bad! Lasted me 91000 miles before 2 of the 6 went out!
Au Contraire...
I had 2-3 of 6 Motorcrafts go out before 15k and have had great results with the +4's (to date
5k)
However with that said; I plan to do a cursory pull of the front plugs to check them before it gets hot again.
I may just put in NGK Platinums and be done with it. :rolleyes:
