What's the best plug for single turbo Supra running high boost? I'm running a T-66 turbo and in search for the best plug out there.
Peter Blach? Anyone?

I have been running the NGK 3330's gapped at 0.027. On the NOS i think i might have to gap down a bit more, we shall see. Lots of ppl have been running the HKS iridium's, i haven't tried them yet...

Thanks Peter, What if I don't gap them down to .027? And just use the pre-gap right out of the box?

they are not gapped low enough for top end boost. You can actually feel the difference in power from the gap length, use the stock gap ~.040 and then lower to .027-.032...you should feel the difference in top end. Good luck

Well, you will be dumping LOTS of fuel if you run high boost (25+ psi), if the gap is too high, you will lose the spark. However, the higher the gap, the more power you have, so you only gap down as low as you have too...
