[DeTomaso] spark plugs

[Doug Scott]

The problem I have with any of these "improvements" is that if they actually
accomplished what was claimed, wouldn't the auto makers not jump on the
ideas and implement them in their products?  Auto makers spend millions, if
not billions, to meet CAFE numbers.  Making the ground electrode shorter
would be a no-cost modification at the manufacturers level, and with them
trying to get tenth of a mile per gallon numbers now, that would make the
no-charge change a no-brainer.
The Mazda rotary engine used a twin ground electrode side gap plug(called
surface discharge) for years, so technology has been around for quite a
while now.  I think aircraft also used surface gap for redundancy reasons.

Interesting suggestion to side gap the plugs. Do you need to straighten the
electrode and cut it, as mentioned in the article, or can you simply bend it
a little to move the tip to the side? I suspect that they say to cut it for
*something*, but it seems childlishly simply if you can simply bend it a
little while gapping...
