Description
Spark plug wires are often overlooked, but they’re critical to consistent ignition performance—especially in high-RPM applications where signal loss can cost you power and reliability. The MSD 8.5mm Super Conductor delivers low-resistance construction that maximizes spark energy transfer to each cylinder, while its ferro-magnetic core eliminates electromagnetic interference that degrades ignition timing. If you’re running a tuned engine or racing setup, these wires ensure your ignition system performs as precisely as your tune intends.
