NGK Laser Iridium Spark Plug Box of 4 (IZFR6N-E)

When you're looking to give your engine a tune-up, replacing your spark plugs is a solid move. These NGK Laser Iridium plugs are built to be a direct replacement for your original equipment, meaning they're designed to work right out of the box with your specific engine. They use a fine wire center electrode made from an iridium alloy, which has a very high melting point, making it tough enough for today's engines and helping to ensure a consistent spark.

What's really neat about these is the construction. The center electrode has an iridium tip, which is known for being much harder and more durable than platinum. This helps them last longer and maintain a stable spark over time. Plus, the pure alumina ceramic insulator helps with heat transfer, and the copper core inside aids in removing heat from the plug itself. For added protection against corrosion and seizing, they've got a trivalent metal plating on the outside.

These are sold as a set of four, which is what most 4-cylinder engines need. If your vehicle uses OE fine wire iridium plugs, these are a great choice to keep things running smoothly.
