If you personally change the plugs at the recommended intervals, with the correct gap and correct torque, you are very unlikely to have this problem. It's when people who don't know what they're doing or don't care, install them, that it surfaces.

If you change them at the recommended interval (100k miles, like maybe twice in the life of the car), and torque them properly there will be NO problems...
This is part of the "problem", Ford "short-threaded" the plugs so they would be less likely to seize into the heads in 100k miles (8 years for the average driver), and assuming that at the max they'd be changed 3 times before the car hit the bone-yard...

Yeah I am guilty of not using a torque wrench myself. I did notice however, when I changed to NGK plugs the threaded portion of the plug was longer if I remember correctly.

i have no idea lol. I worked at a marina for 2 years and a boat shop before that and never even touched a torque wrench for spark plugs. I also used to work on small motors like dirtbikes and such. Never had a problem.

bolt on some trickflow heads, you will not have this problem again.
In fact I have a 4.6 in my sedan, it blew number 3 , had that fixed took the head off and all!
Yesterday it blew #7 !SON OF A BIATCH!!!!!!!!!!!
Your gonna need that warranty, if they say its a manufacturing defect, they will fight the claim,

It's actually my father's in title, but he's 85 and I fly it when I can afford it--it's a Cessna StationAir that he's had for over 25 years--310 HP flat 6, he calls it a 3/4 ton pick-up that flies...
