Where is the location of the spark plugs for a 2003 dodge ram 1500?

If you can't see them it's probably a hemi or a magnum engine. They're under the coils and hemi uses 2 per cylinder, while magnum has 1 per cylinder. they fit in a deep well that goes through the valve covers. If it's any other engine. It's easy, just follow the spark plug wires. they're at the ends of them.
