I was looking under the hood and I only saw 3 spark plugs. The manual says it is a V6, the cover under the hood says it is a V6, but I only see the 3 spark plugs. Can you tell me where the other are?

Should have 3 in front and 3 in back near firewall, they are hard to get at without removing other components first.
Remove the cover first (see pic below)
The rear plugs have spark plug wires that attach to the front coils, you can follow them around once the cover is off and you can see them. They are down below the upper intake manifold
