The NGK Laser Iridium High Ignitability spark plug is an OE-style tip upgrade focused on stronger spark performance and longevity. Iridium fine-wire centers provide exceptional hardness and consistent ignition while premium alumina ceramic and a 98% copper core manage heat for reliable starts. High-ignitability variants often incorporate raised platinum ground features, plus trivalent plating and triple seals to protect against corrosion and leakage.
