I installed the Electroair ignition wires on the bottom plugs, and the Slick magneto wires on the top plugs. Supposedly the hotter spark from the electronic ignition makes plug fouling on the bottom plugs less likely. In addition, the engine should run smoother if one of the ignition sources is shut off. The Electroair ignition wires need to be separated by 1/4 inch minimum so numerous looms were required; I bought them from Summit Racing.
