One thing I've wondered about +4 Plugs - it seems to me that all 4 ground 
wires/electrodes cannot be precisely the same distance from the center electrode. 
 Since the spark is going to jump the quickest way it can, only one ground 
wire will cause the spark for combustion (the closest one).  How is that any 
better than a single-wire plug (besides being more profitable for Bosch)?  Sorry 
for the lack of DeLorean-specific content.
