The NGK Iridium IX spark plug is a performance-focused OE-equivalent that delivers extreme ignitability, improved throttle response and durable service life. A fine iridium center electrode—about six times harder than platinum—provides a consistent spark while the tapered cut ground electrode improves starting, idling and throttle response. High-grade ceramic and trivalent plating support anti-fouling and corrosion resistance.
