The reason why it is more expensive than most cars is because the intake plenum which sits on top of the engine needs to be replaced. This requires one to two hours extra work and that's why shops are going to charge you more to replace the spark plugs on a 3.6 Dodge Durango with the Pentastar engine. You can possibly change the spark plugs yourself and save $205-$300.
