    Built for Chrysler 318-360 engines with socket-style boots, this Super Conductor 8.5mm wire set uses a copper alloy conductor wound around a center core to produce only 40-50 ohms of resistance, creating an effective EMI "choke" that keeps interference inside the wire. A silicone/synthetic outer sleeve resists heat, abrasion, and tears, and each wire terminates in dual-crimp 8.5mm spark plug terminals.

    • Wire Diameter: 8.5mm (Super Conductor Series)
