IRIDIUM POWER Denso Spark Plugs IK22FTT Porsche 964 / 993 / 996 / 997 / Cayman

Ultra-fine platinum ground 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 with a 0.4mm diameter. This means that voltage requirements decrease while ignition performance significantly improves. Manufacturer: Denso.
