I've been reading and seen alot of people running the autolite 3923's which are two steps cooler. Would this be better for a turbo application or just one range cooler? Also what should I gap them at. Seems to me most blown cars are running at .035. Is this a good number to start with? Thanks for any help. -Jeff

I use Autolite 3923's in my trick flow heads but I don't run 15psi. None-the-less, they did make 530rwhp on pump gas so they must work pretty well. I have mine gapped at .035. good luck

I run NGK's that are 2 ranges colder. I gap them from .032-.035 and run anywhere from 10-14psi. I don't have an MSD box though just an accell coil. I think if you have a MSD 6al box you can gasp them a little wider.
