DENSO IRIDIUM SPARK PLUGS DENSO IRIDIUM SPARK PLUG

Six times harder than platinum, iridium doesn't melt in temperatures up to 4,000°F. 360° laser welding of the electrode provides a seal that resists wear even in the worst conditions. The ground electrode features a tapered cut and U-groove that form a large volume area for the flame's center. Use the NGK reference chart to order spark plugs.
