Breaking spark plugs?

[Boomyal]

What model year did Ford fix the sticking sparkplug ground tube issue. Was it in 2007 or 2008? This was for the 4.6 V8.

The problem only pertains to the 2006-2008 with the 4.6L and only with engines having a build date before 11/30/07

So this didn't affect the 07 4.0s then?

Doesn't apply to the 4.0L SOHC. Only 2006-08 Explorers and 2007-08 ST's with the 4.6L 3V V8 built prior to 11/30/07.

Thanks. I saw this issue after I bought and couldn't quite figure out if I included or not. This makes me feel better.

Thanks for the post, with all the other issues with the 4.0 that's one less to worry about.
