for though's of you that have changed your spark plugs what have you gone with. I know when I was playing with my boosted ls1 I would go with NGK TR6's

TR7IX is too cold for stock boost on that car, TR6IX would be the way to go unless you up the boost or add nitrous. Once nitrous is added you could look into a TR7IX or even TR8IX.

NGK recommended.

NGK recommended.

I'm sure they work, but NGK also reccomended a TR6 plug for small-medium hits of nitrous when in reality the BR6EF is a better choice since it is non-projected.

I'm pretty sure this is the AC Delco Irdium 41-985 if anyone cares to cross reference; I run it in both my LS1 car and my 3.8 S/C'd SSEi -- in that car its one heat range colder for it which is great since I upped the boost on it.
