What's appropriate for my R100GS Paralever?
Motobins sent me Bosch WR7DC+ which have yttrium electrodes. I have no idea what yttrium is, but it sounds lank expensive and fast.
The BMW service manual I have says to use W7DC.
Clymer says W7DC.
The NGK Catalog says BP6EVX or BP6ES (which is equivalent to Bosch W7DC). I'm not sure what the EVX suffix means, but it's not common.
I think that the "R" in the WR7DC means that the plug is a resistor plug (either plugs or plug caps are designed to have 5k ohms of resistant...normally I think) and if my plug caps have 5 k ohms already, I don't think it's correct to add another 5k.
Right now, I'm suffering from info overload and general confusion.
What are you all using?
