Hi All,

I was hoping that if you are running a turbo g35 you could tell me what spark plug you are useing, everyone says to use one range colder. I dont know what that means, any advice would be awesome thanks.

Using search is your friend. This has been discussed multiple times. But to answer your question im using NGK super copper that are 1 range colder. Just go to advance or something like that and tell them the car and you want 1 range colder. They will take care.of you. Ill get the part number for you when I get home later.

NGK Iridium IX one step colder plugs.

part # LFR5AIX-11 stock # 4469 plug gap .044

you can get these at any autozone or advance auto parts.
