GT and v6 are exclusive. GT has a v8, base has a v6. You are better off posting in engine tech. I used AC delco for my GT. They aren't expensive.

Per the owner's manual page 11-13... General Motors 12597464 or AcDelco 41-990.

For whatever it's worth, the NGK 3186 G-Power is a platinum spark plug and the owner's manual calls for a double platinum plug.
