MSD 31543 Spark Plug Wire Set

Compatible with Small Block Chevy® Sprintcar. This product is not created or sold by Chevy®. Features a helically-wound copper alloy conductor which has only 40 - 50 ohms of resistance per foot.;<br><br>The special copper alloy conductor is strong enough to handle the high current and voltage of the magneto, plus is a much better conductor than stainless steel. Even with its low resistance, the Super Conductor retains extremely high Electro Magnetic Interference (EMI) suppression abilities. By tightly winding the conductor around the ferro-magnetic impregnated center core, the wire creates an EMI choke holding the noise inside the wire while delivering the strongest spark possible.;
