does the 2006 5.4 have the same plug problem as the 04 and 05 5.4

 

yes, the problem was resolved in 2008 models, but even then i wouldn't wait til 100k miles to change plugs

 

i'm buying a 2006 f150 with 70 kms on it, do ya think if i changed them when i get it i would have the plug problem and is there i different plug i can replace them with so i don't have the problem in the future or would you just stay away from that motor and get a 4.6 and less power

 

the 5.4 is a good motor overall IMO, i would change them early. i would replace them with motorcraft plugs, some 5.4's are picky and run like crap with other plugs, not all trucks, but some, but at 10 bucks or so a plug, i wouldn't risk it. if you follow the service bulletin on changing the plugs, it will limit the amount of breakage you will have, but in the end you may still break some plugs.

 

i would take it to the dealer to get the plugs done for sure what do you think of the 4.6 in a truck. and if a plug breaks what does it take to fix it. did you have one break yet.

 

IMO the 4.6 is a disappointment in a fullsize truck, however i am used to having trucks with power, losing 30% hp is a big difference. of the ones we changed only broke 5 total, we changed 6 or 7 sets

 

once a plug breaks how do ya fix it. do you have to replace the head or is it a quick fix

 

They made a special tool for extracting the broken part, espescially for Ford 5.4L.
Here is one: http://www.denlorstools.com/home/dt1...65600_alt.html

There are couple of company who made them but this one is one of the cheapest.

Hope it help !

 

When do you all think its a good time to change the spark plugs? I have 20,500 some on mine now.. I don't want this issue plus if i get it done I am having someone else change them..lol

 

i would say 50k miles is where i would change them at.
