NGK BKR6EYA. = 0.8mm
I was running these on 10psi with stock ECU. No Problems.
Installed an SAFC 2 and my Tuner gapped them down to 0.7mm due to old Stock Coils. No Problems.
NGK BKR6EYA-11 = 1.1mm
I will go back up to 1.1mm soon as I just bought some Brand New Stock Coils.
This will be interesting...
