Its 0.6 mm iridium center electrode and platinum-chip outer electrode lower the required firing voltage for strong ignition under high boost or lean conditions, while the thermal edge and spark-support gap resist carbon fouling. This ISO seat fits a wide range of Japanese turbo and naturally aspirated engines (RB, SR, VG, and similar) calling for an ISO φ14 plug.
