On the top of the valve cover (top of engine) there is a black plastic air box. First, remove that. Once it is off, you will see the top of 5 coil packs across the top of the valve cover. There is one (10mm?) Bolt that holds each one in place. I always like to clean dirt from the area before removing the coil packs. Once clean, remove one coil pack. Once you remove it, look down inside the valve cover and you will see the spark plug. I strongly recommend that you only do one at a time so that the coils DO NOT get mixed up. If they do, the engine won't run. At this point, remove the spark plug using a plug socket and extension. Once removed, take the new plug, make sure it is properly gaped and replace it to the manufacturer's recommend torque. Replace the coil pack and bolt and move on to the next cylinder.

Let me know if you have questions or problems.
