Hey guys could i install my 1 step colder plugs, with the stock pulley and all? and would it be good for the car or would it hurt it? and its the NGK Iridium ones, so i do not know what they are gapped at.

 

You don't need step colder plugs on your car in stock form. Technically if you only had 89 octane and you were in a really hot environment, maybe, but that's not the case.

 

true, thanks man, becuase i wanna see if i change my plugs if its the problem im having with my car, because i have 1 step colder plugs since im doing my build and i was gunna throw them in until i put everything else in but thanks
