Okay, I have searched and searched on here and can not find the info I know I referenced 7 years ago, last time I replaced my plugs. I know after much research at that time I bought NGK 7781 plugs, and there was discussion about slightly different gapping than factory and I had followed this. But I can not remember what gapping info was discussed. Any of the other longtime members know what i am referring to or anyone have any info for me? Thanks!!!
