Along the backside of th intake, there are 2 metal brackets with12mm bolts that hold the backside of the intake, one is on the driver side behind th throttle body area, the other is on the passenger side and goes over ignition coil #1. Remove these bracket bolts. The throttle body and the bolts in the front of th manifold that hold it to the lower intake manifold and you will be able to lift the intake up and out. Do note that the throttle body and intake manifold gaskets are supposed to be replaced here also.
