Plug/Gap for 12+psi?

[Ddrop]

What plug/gap combo is everyone using for boosting over 12psi?
I am currently using ngk BKR6Es @ .032 gap on my setup. I noticed a miss around 4400rpms. Last time I had this problem at 9psi it ended up being that I had too much sparkplug gap. Im wondering at this point if I should go with a colder plug. I tried taking some timing out of the car. that had no effect. Here is the data im getting from the log viewer at the time of the miss:
RPM:4380
Boost:12.1psi
Spark Angle:18deg
Intake temp:91deg F
PW:17
AFR shows a spike- prob because of the miss. before and after my afrs are high 11s/very low 12s.
my static compression is 9:1. Im running 93 octane.

Boostin 11-12 psi using ZFR7F's at .027", get a random misfire CEL every

once in a while but not feeling it through the powerband.

Use Denso Ik22

NGK ZFR7F gapped at 0.030" and you will be fine. I have run these at 10 psi for over a year now and they are still perfect - wearing exactly as they should be.

Yes, ZFR7F's at .028-.030" should fix your issue.

IK22'S at 14lbs on stock turbo never a miss. It's the same plug the subbie guys use making you know like 300-400hp I think we should be good.

^^^ Holy crap, those are like $10/ea. No thanks, I'll stick with my $3/ea plugs that run just fine...
