Need some advice on spark plugs
I have the part numbers on my home computer, I am at work. There is a one piece, otherwise it would be ridiculous to put the same plug in with this known issue.
There is a TSB, not a recall on this issue, and since almost everyone with an 04-05 experienced breakage, the design was changed to avoid it.

The only one piece by Motorcraft is for for mid 2008 and up. The boots on the plugs are brown rather than black. If there is a one piece, it is Champion, E3 or someother brand, not Motorcraft. You are very misinformed.

I don't see anywhere that it says those are one piece plugs. Plus, I'm pretty sure that is the part number for the replacement plug that came out in 2006 that is just a different heat range. If so, I bought them at my dealer for $10 each.

Does anyone even know what this problem pertained to? How it has been fixed? And what you need to worry about?
From the posts, it seems as if most of you have heard something about it, but never actually took the time to look into the problem yourself. Just relying on what others have said.
Ford made a HORRIBLE mistake and with the new body style, starting in 04, introduced a 2 piece spark plug for the Triton 5.4L V8. This flawed design, led to the plug sticking in the head due to carbon buildup and when removed, had a tendency to break, leaving the threads in the head.
The shield..NOT the threads !!
Ford still recommended changing the plugs at 100k even with this known issue. Most are doing it around 75k-80k. I myself scheduled to get it done next week, I am at 77k and am already feeling the affects of bad plugs.
Ford now recommends changing at 60,000 mi
This problem affected 04-05 production F150s only with the 5.4. There have been a few cases of an 06 having this problem, but because old stock was used.
Ford redesigned these plugs, the updated plugs are a one piece design. Let me say that again. Ford redesigned these plugs, they are now a one piece design.-------NOT !!
If you went to do a plug change and receive a 2 piece plug, you have received dead stock. The new ones have a different part number. If you try to look up the old part number, it will come up invalid. fordparts.com, will only list the new part number anyway to avoid confusion.
The 5.4L was designed for the Motorcraft part, but people have found success in other brands, to each their own for that.
I only post this response, because it seems as though those who commented were not fully educated on this subject.

Oh well, let's lighten up on the guy. I'm sure his face is red enough by now. It woulda been funny if there really had been a new one piece plug that got by all of us. Whoosh! Woulda been at least half a dozen red faces at that point.

Don't know what to do 138,000 mile same plugs
I have a 2004 FX4 scab and have 138,000 hard driving miles, stop-n-go work truck, not highway miles. I love my truck but can't see spending the money to pull the heads to change spark plugs. Who is the best to take it to, or should I trade it. I would feel guilty selling it to some one knowing that the plugs are an issue. The truck still looks good but the tran and diff have had some issues also.

Well, I can certainly admit when I am wrong and now obviously is one of those times. I apologize for coming off like a moron. I was certainly given very bad and useless information by what I thought was a reliable source.
My face is red, I concede defeat. I hope there are no hard feelings fellas.
