Answer
You'll need to remove the intake plenum to replace the rear three plugs.  There are three 12mm bolts holding the plenum to stabilizing brackets in the rear and seven 12mm bolts/nuts holding the front of the plenum to the lower manifold.  You'll need to disconnect the electrical connectors and the fuel regulator vacuum hose and pcv hose.  Once you've got those items disconnected and the air box out of your way, you can lift the plenum off the lower manifold and rotate the passenger side upward to access the plugs.  If you leave the coolant hoses on the throttle body, you'll avoid making a mess and having to bleed the cooling system.

Be sure that you do not drop anything into the intake manifold when the plenum is off.  It's recommended to cover the openings with rags as necessary.
