Remove plastic shield. Disconnect air inlet at throttle plates. Remove stud on driver-side of plates. Bend or remove bracket out of way. Loosen all (6) 13mm head bolts but do not remove. Unplug all elect. connectors @ coils. Remove hold down bolts on coil. Raise plenum on troublesome coils just enough too clear. Replace plugs and reverse proceedure.
