Slotted spark plug holes

Post by RotaryDane »

Saw this on youtube a while ago and it made me wonder.. http://www.youtube.com/watch?v=m3pCLjHZmhMAs far as I am told the offset combustion cavity does not yield much benefit, Mazda have already toyed around with the idea, but the slotted spark plug hole might yield better milage and cooler exhaust. But what do I know? smiley What is the veterans take on the idea?
