8.5mm Super Conductor Wire- 25'

The MSD IGNITION 8.5mm Super Conductor Wire is a high-performance ignition wire designed for automotive enthusiasts and engine builders who demand reliable spark delivery under demanding conditions. This 25-foot spark plug wire features a spiral core construction wrapped in silicone insulation, engineered to resist heat, ozone, and vibration while maintaining consistent electrical conductivity across the length of the wire.

The 8.5mm diameter and spiral core design work together to minimize radio frequency interference and voltage drop, ensuring clean spark signal delivery to each plug. Silicone insulation rated for high-temperature environments provides durability in engine bays where traditional rubber wires fail. The red color aids in identification and adds professional appearance to exposed engine builds. The 25-foot length accommodates multiple cylinders or long-run installations common in street rods, race cars, and custom engine applications.

This wire is ideal for builders and tuners constructing high-output engines where ignition reliability directly impacts performance. Whether used in domestic V8 hot rods, vintage muscle car restorations, or competition drag vehicles, the Super Conductor wire delivers the consistent spark that modern ignition systems demand. MSD's Super Conductor line is recognized in motorsports circles for wire quality and longevity in both street and track environments.

The 25-foot spool format allows installers to cut wire to exact lengths needed, minimizing waste and ensuring proper routing without unnecessary slack. This makes it suitable for custom layouts and multiple wire sets within a single spool, giving builders flexibility in their wiring strategy.
