Best Prevents Fouling Organisms

NGK LKAR7BIX-11S Iridium IX Spark Plug (93501 Iridium Ix), 4 Pack

Designed specifically for the performance enthusiast, Iridium IX offers extreme ignitability, improved throttle response and superior anti-fouling.
The 0.6 millimeter 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 provides superior anti-corrosion and anti-seizing properties.

Solid copper core for greater spark, superior heat dissipation and conductivity.
Corrugated ribs on insulator prevents flashover.
Dual ground electrodes for more consistent spark.
Triple gasket seal eliminates combustion gas leakage and the Zinc dipped shell prevents corrosion.

Designed to operate over a much wider heat range than ordinary plugs.
High alumina ceramics for better heat transfer and electrical insulation.
Solid copper core and nickel tipped electrode provide a longer plus life.
Patented triple gasket sealing process eliminates the possibility of combustion gas leakage.
