Hey, i am running a 100hp NX wet kit on my 91 GT and i was wondering what plugs i should run. I am going to be running NA 99% of the time, so i heard that if i run a colder plug, it will run like crap when NA. So since i am running only 100hp, do i need to run a colder plug, or can i run the stock heat and just run a closer gap?
Thanks
Thanks
