NGK Iridium/Platinum Spark Plug Box of 4 (DILFR6D11)

The center electrode on these NGK spark plugs is tipped with an iridium alloy, which is six times harder than platinum. This makes them incredibly durable and helps maintain a consistent, stable spark over a long time, even in today's high-tech engines. They're built to be a direct replacement for your vehicle's original equipment spark plugs, offering the best combination of performance and longevity.

NGK uses a pure alumina silicate ceramic insulator for superior strength and better heat transfer, helping to prevent overheating. The pure copper core inside also aids in heat removal. For added protection against corrosion and seizing, these plugs feature a trivalent metal plating. The ground electrode has a raised platinum pad to ensure even wear, which is especially helpful for distributorless ignition systems and contributes to improved spark performance.

These spark plugs fit a range of Lexus and Toyota vehicles, including models like the Lexus ES350, Toyota Avalon, and Toyota Camry. They are recommended for vehicles originally equipped with OE DFE iridium alloy plugs, and the triple seals are designed to prevent leakage.
