Uh, unless someone stuffed one in with a shoehorn, the Chrysler 300M never had a hemi engine. the 300 M (1999 - 2004) came with a 3.5 liter V6. Look along the black intake manifold for a small, squarish black thing that has a 2-wire harness attached to it and is screwed down with 2 star-drive screws. that is the coil, as this is a coil on plug type of construction meaning no distributor or plug wires. each spark plug has its own little ignition coil sitting on top of it. Carefully remove the wiring harness and unscrew those 2 star drive screws, then twist and pull the coil pack upward and off it will come. Look down the silver, metal barrel and you'll see the spark plug terminal way down there. you'll need the correct sized socket and an extension for your 3/8 drive ratchet wrench. when you replace the plug, be sure to use anti-seize compound since these are aluminum heads and you sure don't want to strip those threads! If its a HEMI they are located in the middle of each valve cover

Changing spark plugs is an important task. To do this, disconnect the battery and spark plug cables, and remove the old spark plugs. Next put in the new spark plugs, and reconnect the spark plug cables and then the battery.
Yes.
The spark plugs are under the plug wires in the middle of the valve cover.
