I was interested in this also called COBB before I flashed with the AP they said as have other threads that the best are stock. I believe there may be one other company that makes them for the x but everyone says just say with the stock plugs.

Not sure, I would also be interested to know maybe some one else can chime in. I asked Cobb because many times its better to run a step colder plug when running more boost. They said the stock are the best out right now that was about 3 months ago.
