thanks guys for all your input! I'm new on here and this seems like a really informative site! I've read alot of horror stories on here about the spark plugs breaking off, so i'm alittle nervous about whats to come! I guess i'll just hope for the best! hopefully all of the advice i have read on here will make the job easier! I bought my truck a few months ago used with 107K on it, and it ran great! Since then I have 112K and changed the ball joints,rotors,calipers,tie-rod ends, and tires! Now i have a misfire on the #2 cylinder. I am hoping it is just the plugs! Thanks again for your advice!

 

 

denso iridium are by far the best plugs i have EVER ran in my 5.4

 

They don't make those for the 3v........your ONLY choices are MC, Autolite, Champion, and Brisk.

Here is a thread that I posted about my spark plug change, maybe it will help you out with yours.

 

And now you can add the E3 Plug to this list (E3.70)
