The TSB pertains to ALL 5.4 3v 2004 and 2005 models and not dependent on where they were built.

thanks

well do you advise that as something to go ahead and do now to get the antiseize on the threads just for future changes? i was reading the thread about the guy who has only highway miles on his truck, does that make a difference? i also heard if you try to remove the plugs while the truck is warm it makes a difference on the removal, is this true or a myth?

Hopefully they do come out if and when I still have the truck when it needs to be done.

The bad news is I've been following this closely, three forums, and of those that have more than 30k miles it's about 70-30 for broken plugs.
That's with 24 plug changes over 30k miles.
And all have reported pop and creak noises at anything over 20k.

One in a hundred? Maybe that applies to plugs changed at 25k. Only a couple have broke plugs before 25k.

Find me anyone that pulled them at 50k with no problems.
If they have, they ain't posting.

Chris
