IRIDIUM POWER Spark Plugs IW24 for Porsche 356 / 911 / 964 Turbo / 924

Ultra-fine Electrode By harnessing the power of Iridium, DENSO is suddenly able to reduce the surface area of the center electrode - the critical component of a spark plug. Unlike a typical platinum plug with a 1.1mm diameter center electrode, DENSO Iridium Power plugs feature the world's smallest center electrode at 0.4mm in diameter. This means that voltage requirements decrease while ignition performance significantly improves.
