The Halo features a globally patented “Halo Ring” ground electrode, with cutting-edge 360° Firing Technology that delivers superior burn characteristics for improved combustion, higher fuel efficiency, and optimum engine performance.

Unlike standard spark plugs that generate a spark at basically the same location each time, the Halo generates rotating sparks that fire in a 360° pattern around the circular electrode.  This advanced firing system has several advantages, including better ignitability, durability, quicker initiation of the combustion process, maximum use of available fuel energy, reduced fouling and misfires, and virtually no gap erosion for a longer performance life.

In addition, the open ring design of the ground electrode plays a major role in helping to improve combustion efficiency.  Since the flame kernel is not blocked by the ground electrode as in other spark plugs, it can travel freely through the ring into the combustion chamber, igniting the air/fuel mixture up to 30% faster than conventional spark plugs.  This results in a more complete combustion and less wasted fuel coming out of the tailpipe, which means better fuel economy and less pollution.  Good news for both drivers and the environment!
