What gap for NGK 6725-10.5 Plugs?
I need to gap my NGK 6725-10.5 plugs. Does anyone know the gap for these? This will be for 30+psi if that matters......

i think it depends on how strong your ignition system is. I used to gap mine anywhere from .025 - .033" The more gap you have the stronger the spark but less gap will be easier to spark across the ground.

I gap my BR10EIX plugs at 0.022. This is a "10" range plug, and I'm running only around 15 PSI vs. your intended 30 PSI, so there will be some differences. I believe that higher boost means that you need either a smaller gap, or a stronger ignition system to get the spark to "go".

On the NGK 6725 series of plugs I normaly run the gap they come with. I've tested it that way all the way to 11k rpm on both alcohol/gas fuels without any problems and that was using MSD 6al's on the ignition.

Is .032" the gap that comes straight out of the box?

not sure for boosted, but on my peri port race car I run NGK racing, and we gap them .025
run at 9800 and use 2 msd 7al , those plugs last forever at that gap, so it seems to work for us....thats on race gas and premixed............at 20 degrees advanced
