Fine wire racing plugs are designed to give you a stronger spark from your existing ignition system. Fine wire center electrode requires less voltage to ionize(jump) the plug gap. This allows a stronger spark which will better ignite the air fuel mixture leading to more power. Fine wire ground electrode to reduce quenching. Nickel alloy center and ground electrodes. Hand made in Japan and constructed to withstand the most extreme racing environments.
