Alright, I got the NGKTR55IX = Iridium version. I looked in a book, POS said 35, I know stock is 50. I already installed them @ 35, I can easily take them out, think I should pull them and do 50? My setup is pretty wild and N/A. It should be making alot of power and at the moment the car is running a lil rich. I dont have my injectors installed yet and about to get it tuned so what gap should I go for?

Mine was blowing out the spark and breaking up badly when I ran the .050" gap. I kept taking it down till it went away and ended up with .030" I may be able to go back up to .035 though. Play with it and see how your car runs in the upper RPMs.

Leave it at .035".
