This micro-discharge burns off carbon deposited on the insulator during prolonged low-speed driving, constantly maintaining high ignition performance of the spark plug.\n\u003cbr\u003eThe ultra-fine iridium alloy center electrode improves electric field strength, generating a more powerful spark with lower voltage.\n\u003cbr\u003eThe spark is concentrated at the tip of the center electrode, ensuring consistently stable combustion and contributing to improved fuel efficiency.\n\u003cbr\u003eType: Double Precious Metal\n\u003cbr\u003eThread diameter φ14.0mm\n\u003cbr\u003eThread reach 19.0mm\n\u003cbr\u003eHexagon size across flats Hex 16.0mm\u003c\/p\u003e\n\n\u003cp\u003e■Image Disclaimer\n\u003cbr\u003e*Images are for illustration purposes only.
