NGK BKR8EIX IRIDIUM SPARK PLUS PACK OF 4

Built for drivers who demand peak engine performance, the NGK BKR8EIX Iridium spark plugs combine advanced metallurgy with precision engineering. The ultra-fine iridium center electrode maintains a stable spark under intense combustion pressures, while the iridium alloy's exceptional melting point handles the demands of modern high-performance engines without degradation. Trivalent metal plating shields against corrosion and thread seizing for extended lifespan. Corrugated rib design eliminates flashover risks, while the pure alumina silicate ceramic insulator maximizes strength and thermal conductivity. A copper core efficiently dissipates heat, and triple-seal construction prevents any fuel or oil leakage. This 4-pack ensures reliable ignition across all cylinders. Perfect for enthusiasts seeking durability and consistent performance.
