$40 for spark plugs? I seem to remember paying around $500 to have them changed on the Hemi in my wife’s 300C and my Hemi Grand Cherokee.

That is because the Hemi uses 2 spark plugs per cylinder to meet emissions unlike most gas engines that just use one per cylinder. You probably also paid for wires and coils too. Although $40 is very low for most modern engines.
