What makes the iridium center electrode special?

The iridium alloy has an extremely high melting point, which allows for a fine wire design. This fine wire electrode ensures a consistently stable spark and offers durability six times longer than platinum.

Why is the copper core important?

The copper core is essential for heat removal. It helps prevent the spark plug from overheating, ensuring reliable performance and longevity.

Does this box include all the spark plugs I need?

This box contains four spark plugs. You'll need to order four for most multi-cylinder applications. Always confirm the number of spark plugs your specific vehicle requires.

Product Details

The iridium alloy center electrode in these NGK Laser Iridium spark plugs has an extremely high melting point, making it well-suited for today's high-tech engines. These are OE replacement plugs, meaning they are built to the same standards as what came from the factory. They are designed to offer a good balance of performance and how long they last.

NGK uses a pure alumina silicate ceramic insulator for superior strength and better heat transfer, helping to prevent overheating. The center electrode is a fine wire design, which helps ensure a consistently stable spark. For even wear in distributorless ignition systems, most of these plugs also feature a platinum pad on the ground electrode. The copper core aids in heat removal, and the trivalent metal plating helps prevent corrosion and seizing.

This box contains four spark plugs, suitable for many multi-cylinder engines. If you're looking for a reliable replacement that offers improved durability over standard platinum plugs, these are a solid option.
