It is a plate that is mounted between the throttle body and the upper intake manifold. It looks like an aluminum spacer from the top. I recently learned that it was put there to keep the throttle body from freezing at low temps. Apparently chinks of ice were foring in cold weather testing and blocking the TB so it wouldn't close. I havn't heard of this actually happening to anyone who has removed it, but I guess it was only recorded as occuring below 0 degrees. The plate is also a bit of a restriction in the intake and has 4 or 5 hoses running to 2 different plates that get cracked and leak.
