    Its not that difficult but you have to remove the coils that sit over the spark plugs. They screw off and then you have to twist and pull the rubber spark plug covers. You'll need a spark plug socket and a 6" extension for your socket wrench. Make sure you use anit sieze grease on the spark plugs before you install them as it will prevent them from friezing in the heads. I suggest you get a Haynes or Chilton repair manual for 20 bucks if you are going to do these maintenance tasks yourself. They pay for themselves in just the first repair. Good luck!

    NOTE : This engine has aluminum cylinder heads. Do not remove the spark plugs from a hot engine, allow it to cool first. Removing the spark plugs from a hot engine may cause spark plug thread damage or cylinder head damage.
    Remove the ignition coils.
    Remove the spark plugs with a spark plug socket. IMPORTANT: Remove any water and debris from the spark plug holes before spark plug removal.
    Inspect the spark plugs. Refer to Spark Plug Inspection.
    Gap the spark plug, using round wire type spark plug gap gage. Adjust the spark plug gap to 1.1 mm (0.043 in).
    Install the spark plugs with a spark plug socket. NOTE: Refer to Fastener Notice in Service Precautions. IMPORTANT: DO NOT coat the spark plugs with anti-seize compound. Over torquing could occur and damage to the cylinder head threads may result. Tighten the spark plugs to 18 N.m (13 lb in) .
    Install the ignition coils.
