Find a real racing plug that has a colder range than the current OEM plugs and see how a bare or Copper, non-resistance electrode plug works for you.
Also, my preference have always been the racing plug offerings from NGK or Autolite.

Thanks but there are no plugs in their racing series that will fit. I run a 14mm tapered seat with a 1 inch reach plug.
I need the resistor plug so it doesen't interfere with the ECU.
