Just talked to a service advisor at Ford, they said that I shouldn't have any complications when I change my plugs and that its only in the 5.4. I'm skeptical though since I was told different last time I was here. Would like to see what everyone else thinks. I btw I have a '04 4.6

 

your all set. its the 5.4's only and evin then its rely no that big of a deal the tool to remove them works rely good. more of a pain in the *** than anything

 

Wells that's a relief to know. I'm going to just do it myself instead of throwing away $300 bucks! I've been putting it off for such a long time too! Lol

 

yea its way to easy of a job to warrant paying 300$ took me maybe an hour and a half to do it on my 5.4
