NGK RACING PLUG R0409B-8 7791

NGK Iridium IX Spark Plug - R0409B8

Experience the pinnacle of spark plug technology with the NGK Iridium IX Spark Plug. Engineered by the industry leader, this spark plug is designed for ultimate performance, especially in demanding racing environments. The ultra-fine wire iridium center electrode is significantly smaller than conventional electrodes, requiring less voltage to initiate a spark. This not only provides a stronger spark for improved ignition of the air-fuel mixture but also reduces the strain on your ignition system, extending its lifespan.

Featuring enhanced metal shell plating, this spark plug offers superior corrosion resistance, ensuring durability even under extreme conditions. The fine wire iridium center electrode and fine wire nickel angled ground electrode work in synergy to deliver exceptional ignition performance. Each spark plug is meticulously handcrafted in Japan for unparalleled durability and reliability.
