It is the ignition loom that keeps the spark wires together as they come from the magnetos. And it protects them from engine heat as they pass between the cylinders. Some soft aluminum tubing from K & S about 1/8'' – 3/16'' OD polished up or painted with chrome paint. Just pull (stretch) it as you form it around an appropriate diameter object. You can simulate the welds with epoxy. Note the wire exit from the ring at the bottom of each cylinder of both engines.
