NGK Laser Iridium Spark Plug Box of 4 (ILNAR8B7G)

This box contains four NGK Laser Iridium spark plugs, part number ILNAR8B7G. These are designed as direct replacements for your vehicle's original equipment, offering a solid combination of performance and long service life. They are built with an iridium-tipped center electrode, which is significantly harder than platinum, and a platinum pad on the ground electrode to ensure even wear, especially in modern ignition systems.

The pure alumina silicate ceramic insulator helps with heat transfer and provides superior strength, while the trivalent metal plating resists corrosion and seizing, making installation and removal easier. A copper core is also included to help remove excess heat, preventing the plug from overheating. These features work together to ensure reliable starts and a stable spark, even in high-tech engines.

NGK Laser Iridium spark plugs are a popular choice for many vehicles, including models like the Buick Cascada, Chevrolet Cruze, and GMC Terrain. They are intended to meet the high standards of today's engines, providing durability and consistent performance.
