what heat range should i get?
Anyone got the NGK part numbers to use?
depend on what you drive for a daily drivencar
on a stock setup till 10 to 12psi driven daily it's ok
but if you go higher then that for daily driven or different setup it will foul them
If i were you i would run 8's to be un the safe side but you can run the 7's also but at that 7psi and depend on the weather if its cold or not . Have one thing in mind if its a hot sunny day it will affect your engine so the colder the plugs for those sunny day the better but at night if its cold the colder your plug the more you can race with your car cause the plug dont get hot as quickly
