From what I can tell, the 8E is the stock plug and the 7E is a hotter plug. If the plug runs hotter, does this mean the insulater is shorter and retains more heat in the tip? How would that do for a bike that is running a little rich?? Sometimes I can't find 8E plugs at "non-Ducati" shops or auto stores when I REALLY need them. So that's when I thought about the 7E plugs since most jap bike shops have that plug in stock. Not that I plan on running these plugs all the time, but if I have fouled out a set of plugs or was tinkering with the choke too much. ???

Just get the 8s. I've got small pile of DCPR8EVX plugs on hand...

What's the diff between the "E" and "EVX"

I don't know about EVX but EIX is an Iridium plug (premium).Anyway don't use hotter plugs cause you may have pre-ignition problems and damage the engine .It's better to use DPR9 than DPR7.

E = standard tip
EVX = fine electrode platinum
EIX = shrouded iridium covered tip
