NGK Iridium IX spark plugs are engineered for performance enthusiasts requiring superior ignition response. The fine-wire iridium center electrode provides a high melting point and extreme durability—six times harder than platinum—allowing for a consistently stable spark even in high-heat environments. A tapered cut ground electrode reduces quenching, which improves flame kernel expansion for faster starting, smoother idling, and more precise throttle response.

• 0.6mm fine-wire iridium center electrode for maximum ignitability
• Trivalent metal plating offers superior anti-corrosion and anti-seizing properties
• Tapered cut ground electrode improves spark delivery and reduces electrical quenching
• Exceptional anti-fouling characteristics for cleaner combustion
• Direct upgrade for factory nickel alloy spark plugs
• Manufacturer Part Number: CPR8EAIX-9
• Quantity: Box of 4 spark plugs
