The most powerful magnetos demand the best spark plug wire. This MSD 8.5mm Super Conductor wire set features a helically-wound copper alloy conductor with only 40-50 ohms of resistance per foot, strong enough to handle the high current and voltage of a magneto while retaining high EMI suppression. A proprietary silicone and synthetic sleeve resists high heat and abrasion in this tight-fit sprint car application.
