Heat pumps with spark plugs?

Personally I don't see the point. The only area likely to be improved by spark plugs is the idle. Most of these cars idle fine forever with the plugs MB specified at a great savings in price. The only reason I can imagine changing to a different plug would be to extend their lives and avoid the labor costs of replacement. Since the cost of labor is way more than the cost of the standard plug.
