Ok if any of you have changes plugs in a ford 5.4L 3V you know why i'm writing this..
I work at ford dealership in eastern,ontario,canada i have done about 30 of them now
The best way to get them out i found
Step 1: Do an engine flush (we use teraclean) removes carbon
Step 2: after flush run the piss out of it for about 30 mins
Step 3: park vechical overnight
Step 4:Push vechical in don't even start it
step 6 change plugs
this seems to remove and or soften the carbon build up on plugs so you don't break them off in the chamber.
Now of course this is not a guarantee this is what i've been doing seems to be the best method so far if you have any other please share.

IF YOU BROKE OFF THE PLUG OFF IN CHAMBER AND NEED FORD TSB FOR INSTRUCTIONS TO REMOVE IT EMAIL ME hemi_man_80@hotmail.com and ill mail you the TSB in .PDF format(adobe reader)
