MSD Ignition 31249 Custom 8.5mm Spark Plug Wire Set for SB Chevy GMC

The MSD 8.5mm Super Conductor is the ultimate performance wire! Its extremely low-resistance combined with the ability to suppress Electro Magnetic Interference is a combination that defies the common laws of physics.\nLess 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.\nThis combination is encased in a heavy duty sleeve that will wit'stand abrasion and high temperatures. Cap off each end with our Dual Crimp Terminals and you have the best wire available.
