It burns off carbon deposits on the insulator from prolonged low-speed driving with micro-discharges, maintaining high plug ignition performance at all times.\n\u003cbr\u003eThe fine-diameter iridium alloy center electrode improves electric field strength and generates a stronger spark at a lower voltage.\n\u003cbr\u003eSince the spark is concentrated at the tip of the center electrode, stable combustion is consistently achieved, leading to improved fuel efficiency.\n\u003cbr\u003eType: Double Precious Metal Type\n\u003cbr\u003eThread Diameter: φ12.0mm\n\u003cbr\u003eThread Length: 26.5mm\n\u003cbr\u003eHex Size: 14.0mm\u003c\/p\u003e\n\n\u003cp\u003e■Image Disclaimer\n\u003cbr\u003e*Images are for illustrative purposes only.
