Spark plugs for a '99 E-320 (W210)
 

Hey guys, I recently called the dealership about purchasing spark plugs for my 1999 E-320. They said to make sure I purchased the ones made by Mercedes because they have a different resistance (which is patented) than the replaccement ones sold elsewhere.
Is there any truth to this? Should I definitely stick to the OEM spark plugs for this reason?

Thanks

Does any one out there have an answer for this?
Thanks

Sorry I don't have a direct answer for you. It used to be that MB plugs were unusual in that they were non-resistor plugs. I am not 100% sure this is the case any longer. The 112/113 engine plugs DO have the MB star on them, making them at least a little "special", but if it really goes beyond just the star I am not sure. MB has changed the part numbers a couple times for this application, and usually they need a pretty good reason to change. For my own piece of mind, I'd go with the MB plugs. The current recommendation is a Beru "PLATIN" platinum spark plug.
