I actually think that the 08's are different and have a 1 piece plug. I will find out soon because we are changing a buddy's plugs due to the fact he purchased new coil packs.

Presently I'm doing a research about the problem plug removals on the 5.4. So far the information I'm receiving does not indicate that carbon is the problem on removal. Ford should have never stated that these plugs were 100k plugs. Dis-similar metals tend to seize by 100k miles and the answer appears that we should be changing the plugs in the 60k range instead of 100k. I have two folks helping me with this, both of which work for Ford in different environments. I myself have an 04 5.4 and so you can be assured that I'll do the best I can to seek an answer. I work in an automotive job and being on the inside sometimes has its advantages when true answers are to be had. Also the folks I speak to indicate that we should be changing our tranny fluid at 30k (like the old days).

Had to take my truck to the dealer for the plug change. They broke three plugs in removing them. I bought it used (102K) and it was not taken care of by the last owner. (imo) But the dealer said "its a bad design we won't charge you extra for them breaking". We shall see when I get the bill. The truck has been there since Tuesday morning and it's Friday. I also replaced the 4wd solenoid (or whatever its called) that sits on the firewall behind the battery, next to the computer.

At any rate I would HIGHLY suggest not leaving the plugs in 100K. I will never do it. And I also strongly agree on the transmission fluid as well. Can't hurt, right?

hey i have an 07 with the 5.4 with 60,000 miles on it and just found out about this site and the sparkplug problem today. my question is are there any after market 1 piece plugs that can be installed instead of the original 2 piece plug

Do a search on this site for "brisk" and you should find some that have part numbers and brands for you.

broke two plugs and i was able to get one out but not the one under the firewall because of the way it broke. If the electrode does not come out you cant get the removal tools to work. The dealer couldn't remove it either and ended up pulling the cab off the truck. Once they could see down the hole they were able to see the plug and chip away at the porceline to remove the electrode and remove the piece with the puller. At least they did not have to tear the head off the engine. The cab accually comes off easier than removing the engine A few body mounts, rads and plug in harnesses. You have to purge the air cond. and replace the coolant again though.

Holy crap! I would have never thought taking the cab off would be easier than removing a head!

to get the head off you would have to lift the cab up a little anyway ,then remove the head. the head gasget and new head bolts cost $400.00 and change In Canada.at least the engine did not have to be disassembled. you would be supprised how the cab ,hood, fenders etc come off in one piece

I have my truck back now with the cab reinstalled and Champion 7989 plugs in it and it runs just like new. There is no way i was putting Ford plugs back in this truck. So far the Champion plugs are running great and are one piece design. They are double platnum also so they should last a while. Pulling the cab saved me $ 700.00
