The 8.5 mm "Super Conductor Wire Sets" are designed specifically to fit race engines equipped with headers or an MSD distributor. They are custom-made to be routed behind the block, under the headers and to the spark plug, giving the engine an extra clean appearance as well as protecting the wires from making contact with the headers. Set includes terminals for engines with early and late-type distributor caps. Straight and 90° boots and terminals are factory-installed on one end.
