This burns off carbon adhering to the insulator during prolonged low-speed driving with micro-discharges, constantly maintaining high ignitability of the spark plug.\n\u003cbr\u003eThe fine-diameter 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 precious metal type\n\u003cbr\u003eThread diameter: φ12.0mm\n\u003cbr\u003eThread reach: 26.5mm\n\u003cbr\u003eHexagon size: 14.0mm\u003c\/p\u003e\n\n\u003cp\u003e■Image Notes\n\u003cbr\u003e*Images are for illustration purposes only.
