NGK Iridium Spark Plug Box of 4 (IFR5E11)

When it's time to replace your spark plugs, especially if your vehicle came with fine wire iridium plugs from the factory, NGK Laser Iridium plugs are a solid choice. These aren't just any spark plugs; they're built to provide a stable spark for consistent engine performance and are designed for long life.

The center electrode uses an iridium alloy, which is much harder than platinum and can handle the high temperatures found in modern engines. This means you get a durable plug that maintains its gap well over time. The pure alumina ceramic insulator helps manage heat, and the copper core aids in removing excess heat from the plug itself. Plus, the trivalent metal plating on the outside helps prevent corrosion and makes them easier to remove down the road, which is a nice touch during future maintenance.

This set comes with four plugs, which is what most 4-cylinder engines need, and they fit a wide range of vehicles. They are an OE or equivalent replacement, meaning they meet the same standards as what your car came with from the factory.
