IRIDIUM POWER Spark Plugs IW24 (6-PACK) for Porsche 356 / 911 / 964 Turbo / 924

Ultra-fine electrode By utilizing 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 plug with an 1.1 mm diameter center electrode, DENSO Iridium Power spark plugs have the world's smallest center electrode with a diameter of 0.4 mm. This means that the voltage requirement decreases and ignition performance is significantly improved.
