Other than this chat room, I haven't read/heard about this anywhere. I know its common on the F-150 though.
Same problem, and it's all over many mustang sites, including here. search will bring it up.

What kind of detriment will it cause my car?
If the plug breaks in the head, your car won't run until what's left of the plug is removed. A special tool is needed to remove the broken plug. If any of the plug pieces fall into the engine, you're talking major bucks to take it all apart and get it out.

I hear that if you take it in to a ford dealer to get new pluggs and the old ones break off inside that its the car owners responsability to pay the extra cost to have them fish them out

I have also heard people saying it is .45 instead of .045
I REALLY need to get this cleared up because I am doing the switch next week.
Can someone confirm the correct gap?
The manual says 40 to 50 thousandths. Most people say .045", my closest wire gauge was .044 so that's what I used. Do NOT set at 450 thousandths (almost 1/2 inch).
I changed plugs today, luckily went fine for me. 2005 with 20k miles. I warmed up the engine, sprayed PB Blaster and let soak for about 1/2 hr.
The first one (pass side nearest grill) was the only one that felt a little stuck. Went back and forth a couple times and had a little squeaking, but came out fine. The rest were no problems at all, came right out.
The guy is an idiot or doesn't want to deal with the questions.
ALL 3 VALVE V-8 FORD MOTORS PRIOR TO A BUILD DATE OF 1-08 HAVE THE SAME ISSUES WITH THE TWO PIECE SPARK PLUGS, I REPEAT...AAAALLLLLL OF THEM. IT DOES NOT MATTER IF IT'S A CAR OR TRUCK. IF IT HAS A 3-V V-8, MOTOR IT HAS CRAPPY PLUGS.
The engine design is the same, but the operating conditions are different. The truck engines are under more load, more often (think pulling). This appears to cause extra carbon build up as the F150s suffer this problem on a greater scale.
I know the local SVT rep @ Ford, his family owns the dealership. When I brought up the spark plug issue, he said that's its never been an issue at his service department (re: Mustangs). The F150s are a different story,

I pulled the plugs yesterday with no real problem. Some of them were in there really good though. That gave me a bit of a scare. Anyway, I am glad that is done. Those crap OEM plugs are exactly where they should be, the garbage.
