what about the zex plugs.
any good. i had the denso iridums in my car (ran great) and put the zex plugs in and felt to run just as good(i put the zex plugs in because of the nitrous ,and did not want detination)
just thought i would see if any body else has tried them
also i have another ? the porcilen on the denso and zex has cracked on me on two diffrent plugs.. what in the world would cause this. i know it is not the nitrous because one of my denso s was crack after a month or so. and the zex plugs cracked after 4 days... mmmmm any body..?? maybe heat ? :noo :noo
