This micro-discharge burns off carbon that adheres to the insulator during prolonged low-speed driving, constantly maintaining high ignition performance of the plug.\n\u003cbr\u003eThe fine-diameter iridium alloy center electrode improves electric field strength, generating a stronger spark at lower voltages.\n\u003cbr\u003eSince the spark is concentrated at the tip of the center electrode, stable combustion is always achieved, leading to improved fuel efficiency.\n\u003cbr\u003eType: Double Precious Metal Type\n\u003cbr\u003eMounting thread diameter φ14.0mm\n\u003cbr\u003eMounting thread length 19.0mm\n\u003cbr\u003eHexagon across flats Hex 20.8mm\u003c\/p\u003e\n\n\u003cp\u003e■Image Notes\n\u003cbr\u003e*Images are for illustration purposes only.
