1. Remove the (black plastic) cover by turning the two clips one quarter turn counterclockwise.
2. Clean up any dirt and oil that have collected around the ignition coils.
3. Use a wrench to remove the nut holding the ignition coil. Remove the ignition coil by pulling it straight out.
4. Disconnect the wire connector from the ignition coil by pushing on the lock tab and pulling on the connector. Pull on the plastic connector, not the wires.
5. Remove the spark plug with a 5/8" (16mm) spark plug socket.
6. Put the new spark plug into the socket; then screw it into the hole. Screw it in by hand so you do not crossthread it.
7. Torque the spark plug. (If you do not have a torque wrench, tighten the spark plug two-thirds of a turn after it contacts the cylinder head.) Tightening torque: 13lbf-ft (18 N-m , 1.8 kgf-m)
8. Install the ignition coil. Reinstall the nut.
9. Push the wire connector onto the ignition coil. Make sure it locks in place.
10. Repeat this procedure for the other three spark plugs.
11. Reinstall the cover.
Specifications:
NGK: PZFR6F-11

As far as inspection goes; if they're cracked, black, grey/white, ashy, goobered with carbon, etc etc. - replace them. If you're unsure, take a picture of your spark plug after you remove it, and post it on here. Someone will tell if they need to be replaced.
