Time to do a spark plug change and don't want to be removing the heads 
ADMIT IT, everyone loves spark plug changes on the 5.4s.

You do not have to remove the heads if you plan ahead. I belong to an F150 Forum and a lot of people can pull them without breaking a single plug. There are how tos!

im a ford tech warm the truck up to temp and then try to pull them. it seems to help a little. the lisle tool works if they do break off. but i have seen the tool break off too and the head had to come off anyways.
The tool will work and works well. But no tool you buy or simple short cuts are going to be 100% with out any carnage. So if you are not properly tooled up to do the job even if the head needs to come off. Have a pro do it.



I guess its the accountant in me.Yes,$700.00 to change plugs on a 3 valve triton to have a shop to do it including the dealer.Ford does not recomend the #7989 spark plugs and most techs do since the #7989 Champion is a one piece design.Autolite's design is the two piece design.
