I am sure they do, but they are not cheap with Auto Zone, I would go on rockauto.com, or check with an independent parts house close to you. FRPP also makes a set of one piece plugs, let me get you the part number in a bit....

Are the HT1's the correct plugs for an almost stock car? I was just looking at the detonation marks on the two left plugs. Left one is horrible, middle one not too bad.
I've just never seen such bad detonation on any plugs pulled out our cars.
You couldn't hear anythig wrong while driving?
I would put a scope down in that cylinder to see what it looks like. Actually, I probably wouldn't. I wouldn't want to know.

Are you sure about this? The only 1 piece plugs I've ever seen are the Brisk or the Champions. NGK is working on one, but they're not ready yet, they recommend using the Champions until theirs are ready.

I'm going to be pulling my HT1s out for some Champion one piece probably in a few months. I sure wish I would have researched this better before buying HT1. 
I used anti-seize so hopefully there will be no problem getting them out. I don't want a repeat of when the stock plugs were pulled (but I had 50K on them and only like 13K at the most on these HT1). Two broke and it took all day to finally get them out.

[QUOTE=moosestang;6728286]A socket and a C-clamp should do the trick.
You must have heard pinging for the plug to be that damaged.[/QUOTE]
No one seemed to notice my post above. Me and you are on the same page.
Almost seems like part of the story is being left out or the OP is totally oblivious to noises coming from his car.
