NGK Laser Iridium Spark Plug Box of 4 (DILFR5A-11D)

The center electrode on these NGK Laser Iridium spark plugs is tipped with an iridium alloy, which has a melting point six times harder than platinum. This design helps ensure a consistent, stable spark, which is crucial for efficient combustion and overall engine health. These are OE replacement plugs, meaning they are built to the same standards as what came on your vehicle from the factory, offering a great 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 also aids in heat removal. For added protection against corrosion and seizing, the plugs feature a trivalent metal plating. The ground electrode has a raised platinum pad, which helps with even wear, especially in modern distributorless ignition systems, and further improves spark performance.

These plugs are sold in a box of four, which is what most 4-cylinder engines will need. For vehicles with V6 or V8 engines, you'll need to order multiple boxes. They are a solid option for many Hyundai, Kia, and Nissan vehicles, including models like the Hyundai Santa Fe, Kia Sorento, and Nissan Armada.
