IRIDIUM POWER Spark Plugs IK22 for Porsche 964 / 993 / 996 / 997 / Cayman

Ultrafine Electrode By utilizing 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 have the world's smallest center electrode at 0.4 mm in diameter. This means voltage requirements are reduced while ignition performance is greatly improved. Manufacturer: Denso.
