NGK SPARK PLUG CR8HIX 7669

NGK CR8HIX Iridium Spark Plug - CR8HIX

Key Features:

• Iridium Center Electrode: The fine wire (0.6mm) iridium center electrode is designed for high durability and consistent spark performance, even in high-performance engines. Iridium is significantly stronger and harder than platinum, making it ideal for modern, high-tech engines.
• Tapered Cut Ground Electrode: The tapered cut on the ground electrode improves spark quenching, which enhances flame core growth and increases ignitability, resulting in better combustion efficiency.
• Trivalent Metal Plating: This plating enhances corrosion resistance and prevents seizing, which is particularly useful for high-performance applications where reliability is critical.
• Copper Core: The copper core aids in heat dissipation, ensuring that the spark plug operates at an optimal temperature and maintains its performance under extreme conditions.
• Pure Alumina Silicate Ceramic Insulator: This ceramic material provides superior strength and better heat transfer, ensuring a stable and consistent spark.
• Triple Seals: The triple seals prevent internal leakage, adding to the longevity and reliability of the plug.
