The WAY Bosch has made those plugs "resistor" plugs WON'T have any effect on their operation. THEY just cost more!

mercedes says that you can use bosch f8dc4 plugs [from the 104 eng] in place of the h9dc with no ill effects.

I've been finding the new Bosch resistor plugs don't sit well in cars that called for non resistor plugs. As such, I bought a large stock or Beru copper core non resistor plugs. Having only run them for a couple of months I can only offer praise. Time will tell how they hold up over the long haul..but given Beru's usual level of quality I'd be amazed if they didn't hold up @ least as well as the Bosch bits.
