Does anyone have to a guide for a how to? Also, would I need the special tool to remove them if I broke one? The GT ones look a lot father down and harder to get at so that's why I was wondering. Thanks.

V6 models don't have the same issue as the GT's. The 4.6L and 5.4L engines up to a build date of Oct or Nov or 2007 have the issue with breaking plugs due to their head and two piece spark plug design.

I'm wondering the same thing.. ever since I bought my car 2 months ago, I've been replacing every little thing that's replaceable, and thought why not do the spark plugs?

Not an issue on the 6 banger...

at what mileage are you guys changing out plugs? just curious

pascal

60K miles.
Ford say at 100K miles but they go down hill after 60K for sure.

The only thing to watch for is when you put them back in. HAND THREAD them in to start. That way you are sure not to cross thread them. A lot of guys grab the socket wrench and start wailing away without starting them by hand first and end up cross threading.

The last one on the passenger side was always the most difficult one for me. It angles back toward the fire wall and you can't see anything. So difficult angle and tight spot. I found using a wobble extension helped.

Thanks for the help guys!

Don't forget to use anti-seize on the new plugs threads.

Yup. And gap them properly, using a standard feeler gauge. I think the gap is .045 .
Just use common sense when removing and putting them in. Like dont pull on the spark plug wire on the wire part (pull the boot), remove carefully, install carefully with some antiseize on the threads, etc.
