NGK Spark Plug BR8EX IX-Iridium

Iridium spark plugs from NGK are currently the technically high -quality solution. They have an iridium alloy on the center electrode. This point is welded with a special method with a laser. The precious metal iridium is one of the hardest metals in the world. It only melts from 2450 ° C and is very resistant to ponkerosion. By using this metal, the life of these spark plugs compared to standard spark plugs is doubled. Because of this precious metal, the center electrode can also be executed with a thickness of 0.6 mm, so substantially thinner. This measure ensures a clear reduction in the necessary inflammatory voltage and helps to improve the expansion of the flame front in the combustion space. Iridium spark plugs generate a self -cleaning effect. Regardless of the operating temperature, there are electrical discharges in the ring opening between the center electrode and the insulator. They remove any soot particles present and therefore guarantee that the inflammatory voltage is not derived.
