It burns off carbon deposited on the insulator during long periods of low-speed driving with micro-discharges, maintaining consistently high ignition performance of the spark plug.\n\u003cbr\u003eThe ultra-fine iridium alloy center electrode improves electric field strength and generates a stronger spark at 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: Semi-precious metal type\n\u003cbr\u003eThread diameter: φ12.0mm\n\u003cbr\u003eThread reach: 19.0mm\n\u003cbr\u003eHexagon size: 16.0mm\u003c\/p\u003e\n\n\u003cp\u003e■Notes on images\n\u003cbr\u003e*Images are for illustration purposes only.
