It's not the end of the world. Our heads are notorious for that because for whatever reason the engineers decided THREE threads was enough to hold the plugs in. Most cars have 6-8 threads... -.-

It'll cost anywhere from $200-$400 for repair at a shop. My cylinder 4 blew a whole back and cost me $357 total.

Same thing happened to me. When I was driving, 2 of my plugs blew out but only messed up the boots, no thread damage luckily. Mechanic said it was bc of wrong spark brand... I had Bosch. Now I have motorcraft and it's good.

I have an 04 GT. How do I know if I have the Romeo heads? I have been scared to change my plugs because of all the horror stories. Also, do I need to go to Ford and get the factory plugs?

All 04 GT had 8 thread count Romeo heads and 4r75w transmissions. Ford made some minor but excellent improvements to the 04 model year.

Yes they is a very small difference with Bosch never go Bosch change all your plugs back to motorcraft! Not ngk cylinder 6 and 7 spit those out best thing if you got these dam stock aluminum heads to motorcraft platinum no mater what !

Keep in mind 01-03 had Romeo heads but only 4-5 thread count for the plug holes. In 04 the Romeo heads had 8 thread count holes. If you are N/A then stick with the OE Motorcraft plugs they are fine with basic mods. I use only NGK TR6 plugs but I'm also running a decent amount of boost and these plugs respond better to tuning and better heat range.

Actually the NKG plug has just a few more threads on it that give you a deeper seat. I had that happen to my 02 the top of the threads were fbar and the motorcraft plug wouldnt grab the remaining threads. I ended up doing the work myself, there are kits online that you can get that allow you to do it yourself, I myself fabricated the tool.
