Super Conductor Spark Plug Wire Set 4 Cyl., 22R For Toyota Trucks 79-92 MSD IgnitionLess resistance means more energy is going to make it to the spark plug to ignite the air fuel mixture. The Super Conductor uses a copper alloy conductor resulting in less than 50 ohms per foot of wire! This ensures that the most energy possible makes it to the spark plug. By helically winding the conductor around a special core, we are able to produce a highly effective choke to keep the EMI inside the wire and away from other electronics. The MSD 8.
