Sorry guys for the catchy title, anyway, I was needing some recomendations on what type of Sparkplug to go with. I found that the AC R43TS was recommended on the Turbo Regal website for mid 13sec. cars, but when I went to Autozone, all they had was the R44TS, which I'm guessing is the same thing but newer. Let me know what you guys are using, or what should I go with for the best performance??? The car is a 86' T-type and is boosting 18-PSI.
Thanks for any advice!
