I just picked up my 1.7 intercooled kit today. KB had it ready and shipped to Hawaii in less then 1 week. After looking through the install guide I have a question (one for now). O.K... the instructions say to use the DensoIridium plugs but I've read numerous posts about using the NGK -1 colder. I just bought the NGK's because while researching the kit before purchase I read numerous posts that the Iridiums were giving problems. Which one should I use? If I use the NGK's what gap setting should I use? (oh, that's two questions). Anyway, thanks for the help...
