NGK Laser Iridium High Ignitability spark plugs combine long life and enhanced beginning-of-life spark performance for drivers seeking OE-equivalent replacements. A fine iridium center electrode delivers superior durability compared with platinum, while alumina ceramic insulation and a 98% copper core aid heat control and reliable starting. Many High Ignitability variants use raised platinum pads or fine wire tips on the ground electrode for even wear.
