Most people use NGKs. I'm not sure if they're the same, I think they are. You can go on advance auto's website and compare part numbers. Those are the right plugs for NA engines, not sure about TIIs.

Use all 9's.

You can use 9's all the way around if you are running over stock boost to avoid detonation. If the car is completely (or close to) stock, just run the 7's in the leading to ensure a full burn.
