NGK offers you Iridium IX Racing spark plugs designed to optimize engine performance thanks to an extremely fine iridium center electrode, enabling a more precise and powerful spark, thus promoting more complete combustion of the air-fuel mixture and improving engine responsiveness, especially during acceleration and cold starts, while offering better resistance to wear and high temperatures, extending their service life compared with conventional plugs and guaranteeing stable performance even under intensive or off-road conditions.
