IRIDIUM POWER Spark Plugs IK20 for Porsche 996 / 986 Boxster / 955 Cayenne

Ultrafine Electrode By utilizing the properties of iridium, DENSO has succeeded in drastically reducing the surface area of the center electrode – the critical component of a spark plug. In contrast to conventional platinum spark plugs with a 1.1 mm center electrode, DENSO Iridium Power spark plugs feature the world's smallest center electrode with a diameter of only 0.4 mm. This results in lower voltage requirements while significantly improving ignition performance. Manufacturer: Denso.
