Greenplugs

The Halo™ Plug is the first spark plug that can generate multiple sparks per firing order and without encountering the quenching effect!

The open ring provides a direct infinite path for the spark to the air/fuel mixture being pushed up toward the plug from the piston, resulting in a quicker initiation of combustion and allowing a more efficient burn.

Result: More Complete Burn of Air/Fuel Mixture
95% (Halo) Versus 75% (Standard "L" Shape)

This yields more power from a given volume of fuel due to more efficient consumption, and consequently improved engine efficiency.
