i have 6900 miles ..should i change mine now?

I have heard about some problems with the plugs..what should i use..part number..

Should i run a cooler plug? Can i do it or just have the dealer deal with it?

If I was you, I would change them now and be safe. Use the Champion 7989. It's a one piece plud and not 2 like the stocks.

Does this TSB apply toALL 2005+ Mustangs?? Mine is a 2007 built in July of 2006 and was just wondering if I need to have my plugs changed - thanks!

yes, all 2005-2007, apparently some 2008s have a changed design.
I own a shop and wont use Champions in anyones car. Including mine. If they work fine, that great for those trying them. I will take a wait and see approach.
Here is theplug stylethat have problems.

Pulled all mine out when i installed my Accel Coils, they all came out pretty easy. Should've changed them then but, i'm gonna wait until fall when i put her away for the winter.

PB blaster is a penetrating oil, you should be able to get it at your local auto parts store. you`ll have to pull a plug and check to see if its the new style.my car is a late 07 with the new design valve covers and it has the old plugs.
