Good advise ! First back them off 1/8 turn and then get your self some Sea Foam and spray into the cavity until it just covers the hex of the plug, and let sit for an hour. After an hour start by loosing a 1/4 turn then tighting back 1/8 turn. Repeat this and they should come out. If you feel resisitance after the first hour let them soak a bit longer. Good luck and take your time !i pulled mine every 10000 miles and had no problem.to many people have had them break.just put some sea foam around each plug and let it soak in awhile.try pulling them.if it gets hard put more foam till they break loose.replace them with the champs 7989.
Well I wouldn't take it to you if you break 1 out of every 3 ... I've done a lot of them and haven't had a plug break on me yet. A lot of groaning and squeaking in the F150s but never had one break.Just like everyone said, be careful.. if your that worried about it, take it to the dealer.. Id say 1 out of every (3) 3vs I do a tune up on a plug breaks in the head.. mustangs are easy to get them out of.. its the f-150s and expeditions that are the bitch. The spray lube I use is made by Loctite, called Freeze and Release. It works very well. Crack each plug loose a 1/8th turn, spray it in the hole, let sit for 15 sec, retighten the plug then remove. Best of luck to ya man.
We get alot of constuction vehilcles here that have not been maintained.. and Texas weather is great for heat. Some guys have key rings of broken plug heads.. so Im not the only one. The first 5.4 3v u get with plugs broken in #4 and #8 will be fun..Well I wouldn't take it to you if you break 1 out of every 3 ... I've done a lot of them and haven't had a plug break on me yet.

The anti seize isn't for the threads .. LOLI have always been told pull the plugs when the engine is warm. Also make sure you put anti seize on the threads of the new plugs. Also if you feel it get tight when you are threading them out make sure you tighten them a little and then continue to back them out.
