All platinum plugs are resistor plugs.

Mercedes has the resistance in the spark plug wire boots, so it you are using platinum (or regular) resistor plugs, you are doubling the resistance, which diminishes the spark.
Look up the Bosch sight,www.boschusa.com there is a non resister plug marked for the 2s and 4s platinum.
