I am looking to change my plugs on my 2004 F150 with the 4.6 in it. It only has 58k miles but being 10 years old and the original plugs I think its about time. What are the best plugs to use? Should I just use motorcraft? I have used NKG on my other vehicles in the past. I want nice plugs but don't want to buy higher priced plugs if they won't do much different than a cheaper plug.

Motorcraft.

I have a 2005 4.6 and changed my plugs with 26,300 miles on it I now have 54,800. I used the Bosch +2's and have had no issues. They're a great plug

I would just stick with motorcraft.

Why would you change plugs with only 26k miles on them?? Just curious.

somebody has money to burn......with 54K miles it's time for a tranny re-build..

Motorcraft and only Motorcraft. Make sure you use a tiny bit of Neva Seize on treads and Dielectric Grease on the boots.

That was right after i bought the truck, then heard of the broken spark plug issue. Wanted to get them out quickly. Of course found out afterwards that the plugs in the 4.6 dont break. I wouldn't have done it so soon had i known at the time the 4.6 spark plugs dont break.

you stated why you did it so early... good enough for me...mite of helped to mention why in the original post ..then there would be no question on why you change perfectly good plugs out...
