Here are steps from the book

REMOVAL

On this engines, spark plug cable heat shields are pressed into the cylinder head to surround each cable boot and spark plug.

1. Always remove spark plug or ignition coil cables by grasping at the cable boot. Turn the cable boot 1/2 turn and pull straight back in a steady motion. Never pull directly on the cable. Internal damage to cable will result.
2. Prior to removing the spark plug, spray compressed air around the spark plug hole and the area around the spark plug. This will help prevent foreign material from entering the combustion chamber.
3. Remove the spark plug using a quality socket with a rubber or foam insert.
4. Inspect the spark plug condition. Refer to Spark Plug Condition in the Diagnostics and Testing section of this group.

INSTALLATION
Special care should be taken when installing spark plugs into the cylinder head spark plug wells. Be sure the plugs do not drop into the plug wells as electrodes can be damaged.

Always tighten spark plugs to the specified torque. Over tightening can cause distortion resulting in a change in the spark plug gap or a cracked porcelain insulator.

When replacing the spark plug and ignition coil cables, route the cables correctly and secure them in the appropriate retainers. Failure to route the cables properly can cause the radio to reproduce ignition noise. It could cause cross ignition of the spark plugs or short circuit the cables to ground.

1. Start the spark plug into the cylinder head by hand to avoid cross threading.
2. Tighten spark plugs Refer to torque specifications.
3. Install spark plug cables to spark plugs.
