I just got my NGK laser Irdiums and plan on replacing this weekend. The Iridiums come pregapped at the factory .30 and say you shouldn't regap irdium. The top portion of the Iridiums are actually platinum and the small electrode is actual irdium.
I'm doing mine at 34k miles. How have your old plugs looked and at what mileage did you change? I heard the 2006 GT plugs have looked pretty fouled up because of the lean settings they started with before the reflash.
