simple answer. I hope you don't have aftermarket wires, cause they will break off and you will need long needlenose pliers to remove the clip that attaches to the spark plug and/or the rubber boot from the wires. if not, then we continue. On a cold engine twist and pull off the wires one by one, don't worry, Toyota wires are marked 1,2,3, and 4 . Insert the 5/8 socket with extension down the tube and remove slowly. pull the plugs out from the soaket and put some lube on the new ones to be installed. hand screw the new plugs on and then tighten with ratchet another 1/4 to 1/2 turn not too tight though. You might think about replacing the cap/wires and rotor (I strongly recommend Toyota parts to avoid problems with aftermarket parts) Good luck
