NGK SPARK PLUG CR7HSA NG4549, NG4549

NGK Spark Plug - CR7HSA (4549)

Key Features:

• Wide Heat Range: Copper wire dissipates heat quickly, cooling the electrode and insulator tip more effectively than conventional plugs.
• Improved Performance: The raised pre-ignition rating with high conduction copper and a long nose insulator ensures stable ignition performance.
• Longer Life: NGK’s design meets the requirements of high-performance engines for longevity and reliability.
• Corrosion Resistance: Trivalent metal plating provides superior anti-corrosion and anti-seizing properties.
• Flashover Prevention: Corrugated ribs on the insulator prevent flashover, ensuring reliable ignition under varying conditions.
• Efficient Heat Management: Pure alumina silicate ceramic insulator ensures better heat transfer and increased strength.
• Leakage Prevention: Triple seals prevent leakage, helping maintain consistent spark plug performance.
