This micro-discharge burns off carbon deposits that accumulate on the insulator during prolonged low-speed driving, consistently maintaining the plug's high ignition performance.\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 φ14.0mm\n\u003cbr\u003eThread Length 26.5mm\n\u003cbr\u003eHexagon Size Hex 16.0mm\u003c\/p\u003e\n\n\u003cp\u003e■Notes on Images\n\u003cbr\u003e*Images are for illustration purposes only.
