Bosch SUPER 4 spark plugs

["Scott M." <scottmo@teleport.com>]

The Bosch Technical Booklet on Spark Plugs (1997 edition) I
was browsing through describes a "new" SUPER 4 spark plug
that has 4 electrodes.

They describe it as follows:

"The Bosch Super 4 spark plug is the most modern
development of already existing spark plugs. It differs
from conventional spark plugs in having Four Symmetrically
arranged ground electrodes. A silver-plated
chrome-nickel-alloy center electrode with a copper core,
and an electrode gap set for the life of the spark plug's
complete service life."

It goes on to describe all the reasons why this is the
latest greatest spark plug, "Improved ignition reliability
due to the possibility of 8 spark gaps (4 air gap sparks
and 4 semi-surface gap sparks) , Self cleaning surface
spark technology and extended heat range." .....yada yada
yada....

 It also mentions that the Super 4 will ignite lean air
fuel mixtures up to lambda = 1.55 (~22 to 1 A/F ratio)

Could this be the successor to the infamous tri-electrode
used on the 10V turbos?

They use a "Q" designation for the quad electrodes instead
of the "T"  for the tri-electrodes so instead of the W7DTC
I assume it would be designated as a W7DQC or maybe a W7DQS
because of the silver electrode. 

Has anyone run across these plugs or tried them out? 

Maybe a cheaper alternative to the F 5 DPOR?
