As far as the gap, Ford originally had them gapped at .040 to .042, then when the newer plugs (SP534) came out, Ford lowered the recommended gap to .030. Most here have been going with the .030.
Are these the coil covers you are thinking about? Less than $10.00 for all 6!

Do the motor craft sp534's come gapped at .030 or will I have to adjust them? How do I adjust them, do I need a special tool?

Some VERY light tapping on a solid surface will knock that gap down very slightly and with a good spark plug gap tool, you can verify it. The little coin looking one will not be good enough. Metal is too cheap and it won't be as accurate as some others can be.

JMHO here............but with you asking what tool to use to gap a plug, how to do it and where to get it...........Please let your Ford dealer do this for you. Changing the plugs on the EB is a LOT more than just pulling off a wire and untwisting the plug.
Do you know what to torque the new plugs at? You could save a lot of money by buying the plugs from Rock Auto rather than your dealer though.

I learn from asking questions. Just as anyone else would. I doubt you were born with this knowledge. I need to get the truck serviced so I may go ahead and have them swap out the plugs anyways.

The first dealer I took mine to wanted $240, the second one did it for $114..... so, I guess I am saying....ask first!
