Buy a pack of plugs, the number you need, buy new wires as you should change those too. Disconnect the negative battery cable. Make sure you do not touch it to the positive cable. Pull the wire off one spark plug (you may have to turn the wire first then pull it off) and remove the other end of the wire  from the distributor cap. Use the spark plug socket and carefully remove the plug making sure you do not cross thread it as it comes out. Then take the new plug and spray a little silicone on the end that screws in (it should already be gaped correctly but check the package to be sure) then  tighten it to the point it stops turning. Do not cranks on it or you may break the plug.  Put the new spark plug wire on it and attach the other end to the distributor cap. Do this for all spark plugs. Do them all one at a time so you do not mess up the ignition timing by mixing up where the wires go.
