Im almost nearing the end of my single turbo conversion, can anyone help me with what plugs i should run?

 

What turbo and boost will you be running and what power figure are you aiming at? these will dictate the plug grade, I ran one grade colder at about 520BHP with no problems, if your looking at more than that I would perhaps try two grades colder, a normal copper core plug will be fine, there is nothing to be gained by fitting iridium plugs, they are just intended for longer service life in engines that have hard to reach plugs.
