Description
Weak spark plug wires bleed ignition voltage and kill engine efficiency, especially in high-RPM applications where every volt counts. MSD’s Super Conductor spiral core delivers lower resistance and more consistent spark energy to all six cylinders, resulting in faster combustion, sharper throttle response, and improved overall engine performance. The cut-to-fit design and universal boot compatibility make this a straightforward upgrade that pays dividends on the dyno or the street.
