I put Champion #7989 plugs in my '06 GT 25K+ miles ago. Hasen't missed a beat yet. I am very happy with the results. I'll NEVER put one of those crap 2 piece plugs in my engine again.

For those who reinstall a two piece plug apply the anti-seize on the metal sheath that is below the threads. Anti-seize on the threads is important too, but the threads are not the reason why these plugs break.

It's important to note that you want to use nickle anti-seize and nothing else. Also be very careful that none gets on the electrode otherwise you're going to have problems.

I really don't see what the big fuss is all about...when it's time to replace the plugs (which will probably be in another 4-5 years...I have 20K miles on her now), I will take it to the Ford Dealer and have them do it. If they break a plug, then it's up to them to remove it...and I should only have to pay what it costs for a routine plug change out...

If you're going to think that way, don't wait so many miles to have Ford do it so the carbon doesn't build up.

They probably break them on purpose to get paid extra - doesn't seem right that they charge you for something they broke.

There's nothing wrong with the Motocraft 2-piece plugs. In fact, from what I have heard, they are probably the best quality plugs you can get for the S197.
Just remove the plugs before 20k miles appears on the speedo, and replace with a brand new set of Motocraft plugs... but this time, add the correct anti-sieze as shown in the TSB.
I've done this and have had no problems at all.

BTW, I just removed the stock plugs for the second time - first time was at 25K miles. I didn't have the Champions at that time, so I put in new stock plugs with anti-sieze. They were a b*tch to get out the first time - very choppy when turning the torque wrench, creaked like an old barn door. Luckily, none broke (followed the TSB). This time, at 48K miles, they came out easy - smooth as silk. So the anti-sieze seems to make a difference. Put in Champions this time - running great, no longer have to think about it. I did put a little anti-sieze on the barrel just in case.

So... With everything I have been reading... Today sweaty and shaking I decided to change my plugs. I was so nervous (and hoping to cause had I broke a plug I convinced myself I was getting new heads) that a plug was going to snap but they actually cam out really easy. Broke them loose and turned them out by hand. What a relief!

My car was built in December '05. What's up. I sure hope it does indeed have the one-piece plugs.TJ
It has black boots on the COP's also
