What a nice dependable plug TBOLTUSA.COM
I ran NGK in the past -like way in the past 1968 and they were so so plug in my book then.
I stayed away from them for more than 40 years and now i`m back to stay.
What a clean running heavy made electrode with the porcelain so perfect it is like a jeweler had made each one.
No miss firing all types of fuels and mixture and not one has shut down .
Dependable Plugs make racing one step easier.
Sincerely: Phil
