NGK 7397 TR5IX Iridium IX Spark Plug, Pack of 4

• NGK Sparkplugs
• Spark plugs
• Longer insulator nose prevents fouling, the corrugated ribs on insulator prevents flashover, and a triple gasket seal eliminates combustion gas leakage
• Trivalent Metal Plating - superior anti-corrosion and anti-seizing properties

Designed specifically for the performance enthusiast, Iridium IX offers extreme ignitability, improved throttle response and superior anti fouling. The 0.6mm laser welded fine Iridium tip ensures high durability and a consistently stable spark and the tapered ground electrode minimizes electrical Quenching Effect. Longer insulator nose prevents fouling, the corrugated ribs on insulator prevents flashover, and a triple gasket seal eliminates combustion gas leakage. Iridium alloy has extremely high melting point, giving it high durability to heat and electrical wear, perfect for today's high-performance engines. Trivalent Metal Plating - superior anti-corrosion and anti-seizing properties.
