The best recomendation I can offer through the research I did is stick with motocraft.
Some other have tried champions or autolites and ended up doing them again after 10k-20k.

Will do! Thanks 88.

i never thought of this before, would this effect my new motor in my truck that i swapped since it is a 2003 5.4l 2v ? it had originally the cop ignition black boots before i swapped to coil system. i have not changed them as of yet since i am waiting for my tunes first. But shortly there after this is since i do not know when or if they were ever changed in this vehicle originally. it had only 38,000 km on engine when i bought it a month ago

Nope!
That's why this is posted in the 04-08 section.
If you have a 5.4 2v then this tsb does not apply.
You just have to make sure you torque yours right so they don't loosen up and pop out.

That's right! He has the spark plug ejection problem, doesn't he? You'd think, with all their experience, Ford wouldn't have created two crummy designs in a row!

I don't know which is worse?
Paying for plug extraction.
Or.
Paying for the install of time serts.

ok great thanks for the heads up with the torque, its usually 25lbs right?

On your applicaction 03 5.4 2V that sounds about right.

Sorry if I am covering a previously covered topic but I am new to F-150's. I just got a 2007 F-150 with a 4.2 v-6 and a manual tranny. I assume from what I have read that I do not have to worry about the "stuck/broken" plug or the plub ejecting from the housing. Am I correct in this?
Thanks.

That's ok!
This is for 5.4L 3V motors.
