Really had no misfires or problems...just wanted to look at and replace. Same plugs in now with .30 gap. Also replaced the boot ends.

Good preventative maintenance, Dawg. Ford did us no favors telling us that it is a 100K item. And the coil boot replacement is new to me. Glad they are cheap and will replace with the next plugs.

I'm same as dawg, no problems, but less miles. I'm at 26k, with 8k of that hauling heavy with my TT.

Been tempting to open up and check them out.

I think that you're due, especially if you have a tune. 30K miles would be the absolute longest I would run them.

No tune, but I figured as much. SP 534's right?
