E3 plugs utilize a diamond-shaped electrode with a revolutionary edge-to-edge design. This patented design delivers a forced edge-to-edge spark discharge that projects the spark into the air/fuel mixture for better combustion. This design also creates a chimney effect that pulls the flame front out into the mixture-not around, like a standard J-wire plug. E3 says the result is more power, improved fuel economy, and carbon is practically eliminated.
