well the ngk v series is what i compared to in every test,,,,, so if you had a back to back test, between v and std, say it,, just dont say im wrong,,, tell what you found... lets be productive here and all try to learn off what each other has found


i have no clue if they make an "ar" series in a 3/8 reach

every pro stock guy i know runs autolite plugs,,, but they prob get them for free,, cause i do..
