IRIDIUM POWER Spark Plugs IK20 (6-PACK) for Porsche 996 / 986 Boxster

Ultra-fine electrode Thanks to the use of Iridium Power, DENSO is suddenly able to reduce the surface area of the center electrode – the critical component of a spark plug. Unlike a typical platinum spark plug with a 1.1 mm diameter center electrode, DENSO Iridium Power spark plugs have the world's smallest center electrode at 0.4 mm in diameter. This means that the voltage requirement decreases and ignition performance is significantly improved. Manufacturer: Denso.
