Spark plugs effect on performance...
About two years ago I put ACDelco Rapidfires in my car and gapped them at .030 for nitrous, I know I know you don't use platinum for nitrous and I never sprayed it but I'm wondering what the effect of the .030 Platinums would be against some NGK TR55s gapped at .050?
Gas mileage? Low end/high end power etc...
TIA
