I am running my 2nd set of Champions. First set was in like 65K miles before I changed them. Zero issues. Installed the 2nd set at 100K miles on my '06. I had one bad plug in this set which Rock Auto replaced N/C. Running like a Champ. No more 2 piece plugs in my engine.

Its not the 2 piece design that sealed the plugs in the head, its that when ford put the plugs in, the porcelain was coated with copper. Under combustion, the copper would fuse to the head, and you've got problems.
Since then, all the OEM plugs have a nickel coating, which doesn't have that problem.
Nothing against you, but what were the champions, like $12-15 a plug? No thanks. I replaced mine 10k miles ago and have had them out 3 times since with not even a squeak. Cost me $60 from AM for the plugs.

I know it's not the two piece design itself that is the problem, but it is a contributing factor. The root cause is carbon build up on the Spark Plug inside the combustion chamber fuses the electrode to the head When you go to pull the plugs out the two piece design breaks at it's weakest point (the seam between the two halves).
The real fix is the late 2008 (almost 2009) head redesign. A one piece plug or coated plug is the band aid.
Regardless, I'd buy champions again. 35K on them and ZERO problems. I've had a couple out randomly every 10K no issues. Piece of mind for this issue - priceless.

I hate to post on every spark plug thread, but after my experience, I will add that the Lisle tool has two purposes. One is to remove spark plugs from your 'stang, the other is to have it shoved up the a$$ of the engineer that designed this plug/combustion chamber combination. I have heard several stories about the 6.2 trucks actually spitting out the porcelain section leaving the threaded collar in the block. At least that would be easier to remove!

I would recommend a double plat plug, with the newer coil packs you actually get a det on the adjacent side of the motor on an exhaust stroke. With a double plat it just allows your system to have a greater spark without screwy resistances throughout the motor. I run them on my m90 '96 stang and it got rid of a lot of my pre-det issues. Just a heads up.
