Tight fit / 90 Degree at plug / 90 Degree at cap designed to meet the needs of Sprint Car racing.
The most powerful magnetos demand the best spark plug wire: the 8.5mm Super Conductor! Our 8.5mm wire features a helically-wound copper alloy conductor which has only 40 - 50 ohms of resistance per foot. The special copper alloy conductor is strong enough to handle the high current and voltage of the magneto, plus is a much better conductor than stainless steel. Even with its low resistance, the Super Conductor retains extremely high Electro Magnetic Interference (EMI) suppression abilities. By tightly winding the conductor around a ferro-magnetic impregnated center core, the wire creates an EMI "choke" holding the noise inside the wire while delivering the strongest spark possible.
The sleeve is a proprietary compound of silicone and synthetic material making it resistant to high heat as well as tough against abrasions.
