NGK LKAR7BIX-11S Iridium IX Spark Plugs (4-Pack)

NGK LKAR7BIX-11S Iridium IX Spark Plugs (4-Pack) deliver unmatched performance for high-performance engines. Engineered with a 0.6mm laser-welded iridium tip, these spark plugs provide superior ignitability, faster throttle response, and consistent spark stability under extreme conditions. The tapered ground electrode minimizes electrical quenching, while the extended insulator nose resists fouling for long-lasting reliability.

Built with a triple gasket seal to prevent combustion gas leakage, these plugs feature trivalent metal plating for exceptional anti-corrosion and anti-seizing properties. The high melting point of iridium alloy ensures durability against heat and electrical wear, making them ideal for modern performance engines. Engineered for precision and longevity, these NGK Iridium IX plugs are a top choice for demanding applications.
