This allows micro-discharges to burn off carbon deposited on the insulator during prolonged low-speed driving, consistently maintaining high ignition performance of the plug.\n\u003cbr\u003eThe ultra-fine iridium alloy center electrode improves electric field strength, generating a stronger spark at a lower voltage.\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 noble metal type\n\u003cbr\u003eThread diameter: φ14.0mm\n\u003cbr\u003eThread length: 26.5mm\n\u003cbr\u003eHexagon socket: 16.0mm\u003c\/p\u003e\n\n\u003cp\u003e■Note on Images\n\u003cbr\u003e*Images are for illustration purposes only.
