Why insist on multi stand copper core wire??
For optimum performance and the elimination of radio noise. Spark plug wires need a specific resistance between the connector on the distributor cap and the spark plug. This resistance is a specific value prescribed by the car manufacture, as well as the specific design of the ignition system. To maintain the ohm resistance European car manufacturers install resistors in the connector at the distributor cap as well as the connect at the spark plug, rather than making the entire wire a resistor. Although not recommended for European ignition systems, a cheaper way to achieve this is to use non resistant connectors and substitute Spiral core resistance wire in place of the multi stand copper wire, which is not recommended for any European vehicles.
