There are 4 bolts on the 2.4 Twin Cam cover on top of the engine. I believe they are 13mm. Remove them, and pull the cover up and off. Under there are the spark plugs. And you will see the ignition system connected as one with the cover.
There are no spark plug wires.
You'll find springs inside of insulator 'boots' when you get in there.
