This plug is resistive. You need a non-resistive plug. Again, read this thread for more info. Only use a plug specified by MB. The fr8dpp33 is not. 99 C280 spark plugs

fr8dpp33 IS the latest plug recommended by mb. call any dealer and have them look up the part number for any 112/113 motor and it will sub to 003-159-94-03. then ask them to open the box. voila! bosch plug and # FR8DPP33! i read your attachment and it did not have FR8DPP33 in the listing. i have a copy of the latest EPC from MBUSA on spark plugs as of MAY06. see attachment.

Interesting. I don't pretend to know a whole lot about ignition systems. It looks like MB is approving the use of resistive plugs in systems designed for non-resistors. Since these are interchangeable, is there any reason to prefer one type over the other? Performance? Service life? Price? Beru plugs are still available as non-resistor. Is there any reason to choose them over the less expensive Bosch resistor type? I asked my dealer and they use the Berus.
I would like to open the attachment but I can't see it.
Thanks, Dan
