1994 E320 (current)
Need definitive resistor vs. non resistor info.
So i am getting mixed info from pretty much everyone I talk to. Can anyone tell me definitively whether or not My 1994 E320 should or should not have resistor plugs. I have heard a bunch of different opinions about it but no documentation to prove the point. Is there any literature out there that shows this info. I have parts stores telling me that the resistore plug is OEM and even some telling me that Bosch doesn't even make a non-resistor plug anymore. I currently have NGK plugs in there that are resistor because that is listed as an OEM spec plug. Anyone who can point me in the right direction I would be very grateful.

NGK website shows a resistor, but I would think the correct NGK would be a non resistor.
I use the copper core NGK BCP6ES or BCP6EFS.
Bosch was the OEM plug, but I don't think they make the non resistor any more.
SOHC typically can use Champion S10YCC, DOHC the Champion C10YCC
