Spark PLug Gap ?!?
Hey guys i just switched out my NGK BPR 8ES for another set of NGK 8es. my other ones were breaking up on me up top.

my question is my old spark plugs i left them the way i got them pre-gapped already. I was wondering for the setup i am running which is a Built 2.0 with Gt35r should i re gap the new plugs to something smaller? Like maybe .024 or .026?

just need some advice

thanks guys.

It depends how much boost you're running, more boost smaller gap.

my tuner set mine at .024

but then when I replaced it with fresh plugs I set it at .0245

I dont know if the .0005 makes any difference, but I'm running a HKS DLI-2 ignition amplifier as well
