Post Side gapped plugs

Anyone ever heard of side gapped plugs? Is it worth doing to a normal street engine?

I ran 'em in the early 60's in the unblown gas dragster. Never noticed any performance benefit. As I recall, a special tool was required to gap the things. Don't bother !

The multi electrode plug is far superior to the side gapped plug for performance, unless you can buy them off the shelf it's not worth the trouble of trying. Have a look at a rotary plug with it's 4 point electrode and the environment they work in and you'll understand their usefulness. They simply work better under fuel flooding plug conditions. Unless your running an Alky engine that needs help igniting a rich charge the modified plug is pretty much useless for the street. A side cut electrode is the Hotrodders first attempt at this type of plug and is not even worth bothering with.
