Looking for a shorter plug than a TR6 Ok I have been fighting this situation back and forth now for far too long now and need to get this resolved so if anyone has any ideas PLEASE help me out.
Back story is I bought a twin turbo car from here about 4 months ago that was in the final stages of everything. Everything runs fine except it has a slight over heating issue at idle, because of cheap fans I believe, and it keeps burning plug boots which is what I am trying to get past so I can move on to other things.
Anyway I have been having someone help me with all of this as I am not really a mechanic and he used to own a shop working on LS cars so I trust his ability but it keeps burning boots 1-3-5-6, the others are ok. He has suggested we try the Accel ceramic plug boots but the end of the plug is so close to the manifold it won't allow it to fit on to it which brings me to the question of is there a shorter plug that I can run to give the boots enough room? I have read that some of the Autolites are shorter but which ones and by how much? We only need a few milimeters to fit the plug boots on.

No. The reach you describe is how far it goes in the threads of the head. with that short of a plug you will almost be a 1/4 inch short going into the head.
What you need is a shorter ceramic on the outside of the plug. You could try an NGK br6ef which is the equivalent of what you have but in a non projected tip. I don't really know how much shorter its going to be for you but you may want to look into those fiberglass covers that go over the plug boots.

I also have a twin turbo car and my boots were getting eaten up. I now use these -

They have a ceramic boot. Its like a clay pot. good for like 2000* continuous. You should be good to go. They are a little bit bigger than a regular boot and dont flex so it makes it a bit challenging if you have to snake it in somewhere

Those are actually the wires we are trying to get to work but they are the 115 degree or whatever, I don't think 90 degree will go on far enough because of the manifold design. Unless they are run down I stead of up they "might" go on if they were pointed down. Are yours run down?
