Where are the spark plugs? I pulled off the plastic top cover, looked all over the engine. can not find them. Help!!! Pictures would be nice.

 

The 4.0 is a coil on plug system. They are located underneith the intake manifold. Once the intake is removed, disconnect the connector from the coil and remove the retaining nut. Remove the coil and the spark plug is down in the hole.

 

Thanks, I thought I was going nuts because I could not even find the plug wires. The intake manifold is removed with the 4-8mm bolts on top?
