btw if you have any trouble finding the socket, the screws have the same size male torx head that the throttle body plate female screws have. TB screws can be made into an opti cap removal tool in a pinch using two nuts of the same thread.

Harbor freight or advance auto are the best places to get them. Get the deepwell set it makes it easier.
