yea, i gapped my vpower #9's @ .030 and they are good. I bet the iridiums could go for .034 or so. My car seems to do ok on the ignition side.

Ya I bought some BKR8EIX plugs and stock gap is 0.032, I an running a 300 ish CTSC setup and my tuner said these are the ideal plugs and to leave them at stock gap. Gapping an iridium plug is a baaad idea.

Im not sure how high a heat range8 plug is good for...

So these should not be regapped? Do they have a tendency to break off when regapped?

I also run BKR8EIX's. They come pre-gapped around .030" and have performed very well for me.

BKR8EIX
Ideal gap is .33 which is close enough to how they come.
I would not try to gap them.

Yes DO NOT try to gap these, would suck having the tip break off in the engine.
