Best plugs for 98 F150 4.6L?
Fist of all, THANKS RACERGUY for the pointers on changing the spark plugs!! I'm not sure I would have been as motivated to change them without the guidance. Anyhow - my question is, what are the best plugs for performance, milage etc? Any suggestions? Thanks for the input!

Autolite & Motorcraft spark plugs are both made by Honeywell,
a division of Allied Signal. Fram is also a division of Allied Signal,
and you are correct about not using anything with a Fram name
on it....

Yes,it is true Autolite and Motorcraft are both made by Allied-Signal,who is owned by Honeywell.But,Motorcraft are made to a different specification then Autolite.Ford has them made to there specifications.How do I know this?I was curious about it,so I emailed www.autolite.com and they themselves sent me an email stating all the above information.
So,if I were to use a plug in my Ford,it would be a Motorcraft.

I would shy away from the NGK Iridium. As soon as I installed them the truck was harder to start. I would guess that the gap is excessive but the instructions said not to adjust the gap because the tip is so small.
They are also very expensive.
I am tempted to find a set of Motorcraft and install them. I find more and more reasons to stay with stock components.

Bob, just curious. Why not use Fram products? Are they junk?

with Fram oil filters......Personally, I'm a believer in using the
manufacturer's OEM oil filter, so I use Motorcraft on my Fords,
and Mann (German filter mfg.) filters on my Mercedes'
