Quick question, I know plats aren't good for nitrous, I'm using a 100 shot. I use the NGK tr6 now and they need to be repalced, NGK now has the iridium plugs that are also one heat range colder. ARe these good for juice, or are they like plats and they shouldn't be used??

Thanks

Platinums are the ones that are not supposed to be good for nitrous.And copper plugs don't last long.I think the iridiums should be great and seen lots used by the import guys with big turbos and spray.Also in additon to the ngk iridiums which up till now were in stock heat range only you can order denso iridiums in several heat ranges lower.They are virtually same as ngk ones maybe a bit pricier but they have a long life.
