Sure there is. By changing them out, you will have fresh plugs so you won't have carbon buildup. Otherwise, you're just going to build on top of the carbon already there. You can also put some nickel antiseize on them to aid with removal in the future. I don't see any reason NOT to change them. Even if you just pull the stockers out and put some antiseize on them.

Ok, you guys scared me.
Are there any disadvantages to going to an aftermarket spark plug? And what's the commonly accepted 1-piece replacement?

Have you ever pulled a plug that has been in a vehicle for 100k? Well let me tell you what I have many times and they are not a pretty site.
Most have no electrode left and the ground strap is usually worn to nothing as well. And that is on a car that was supposedly running fine. Also I have had on occasions where the plugs simply would not come out do to carbon buildup.
I highly advise against any plug being left in for 100k.
50k Tops in my book.
By the way anyone know if Denso or NGK is making plugs for our cars yet in the Iridiums?

(The 07 GT wont be keeping the Ford plugs long, going to change the factory HT0's next month to the one piece)

"TSB 06-15-2 and 06-5-9 cover how to correctly remove the plugs using AeroKrol penetrating spray to avoid separation and how and where to use nickel anti-seize when installing new ones."

Yup! Pretty sweet deal when you can screw something up and then charge the customer to fix it. By the way, I have a brand new set of Autolite HT1 plugs - never touched if anybody needs a set. PM me, very friendly price.

These spark plugs are not cheap. I would rather not waste my time changing out these pricey plugs that still have the factory design defect. I would like to possibly change plugs at 10k-20k miles with factory-spec replacement plugs that are 1-piece and leave it be.

Looks to me a good deal of insurance would be to soak with penetrating oil prior to removal regardless.

This is some Scary Stuff. I have Seen Lots of the Prior 04 5.4 L Trucks Blow the Sparkplug out of the Head. This was due to Lack of Threads in the Head. My Harley f150 Spit one out at about 16k. A new Head was Installed Under Warranty. As Far as the Broken Plugs on The 3v I have not heard of any in our shop. I would advise that you Replace your Spark Plugs before your Powertrain Warranty Expires so there maybe some Recourse if this Happens on your Car. Of course that means you would Have the Dealer Change Them. Also If this Does Happen and you are Charged for Removing Damaged Plugs I would Save Any paper Work as It Could Turn into a Recall Issue in the Future and you could be Reimbursed. If you are Going to Install yourself Use the Anti Sieze Sparingly as too Much could cause an Issue as well. Another thing to Do is to Ask your Dealer Upfront if They Change your Plugs and Break them off are they going to Step up or are you Liable. I will see if my Service Manager has any input on this Also and Post Later!

So what do you guys think? Do we get the Brisk plugs and change them every 40,000-50,000 or so, OR get, say the Autolite HT1's and change out more often..OR will the application of the anti-seize compound eliminate the problem???? This has me very concerned also.
