IRIDIUM RACING Spark Plugs VK22 for Porsche 964 / 993 / 996 / 997 / Cayman

Ultra-fine Electrode By harnessing the power of Iridium, DENSO is able to drastically reduce the surface area of the center electrode – the critical component of a spark plug. Unlike a typical platinum plug with a 1.1 mm diameter center electrode, DENSO Iridium Power plugs feature the world's smallest center electrode with a 0.4 mm diameter. This means that voltage requirements are reduced, while ignition performance is greatly improved. Manufacturer: Denso.
