I have the STG 2 93octane and started with stock plugs at stock gaps because that's what I was told to do by Halim and see if I had misfires first. I had misfires at around 4,200rpm and up so then he told me to get the NGK plugs and gap between .018 - .020. I gapped them the new NGK to .019 and no misfires. It has been good for about a year now.
