How do I change the spark plugs? Do I need any special tools. I have a fairly basic tool set.

Also, keep in mind using only the recommend NGK or Denso plugs that are listed in your owner's manual. The recommended plugs have a double ground electrode. I would stick with those plugs.

If you are going to do this change yourself, I recommend getting a long 3/8 inch drive spark plug socket with an attached extension on it. By that, I mean one that has the 5/8 inch spark plug socket permanently attached to the extension. Many auto parts stores now carry this tool. If you use the conventional type of 5/8 spark plug socket, once you tighten down the plug in the head, the socket usually sticks on the plug when you pull the extension out. That socket can be a real PITA to remove from the spark plug way down in the spark plug well. Also, be sure to purchase some antiseize compound and apply some to the threads of the plugs before you install them in the head. This is very important. You want to be able to remove them from the head when the time comes.
