NGK Iridium Spark Plug Box of 4 (IZFR6F11)

NGK Iridium spark plugs are a solid option for many vehicles, offering a good balance of performance and how long they last. These are built to meet original equipment standards, meaning they're tested to ensure they work well and hold up over time. The center electrode uses an iridium alloy, which is much harder than platinum, giving it a long life. Plus, the pure alumina ceramic insulator helps manage heat, and the copper core helps keep things cool, ensuring reliable starts. The trivalent metal plating on the outside helps prevent corrosion and makes them easier to remove later on.

Many of these Laser Iridium plugs also have a platinum pad on the ground electrode. This helps them wear evenly, especially in modern ignition systems that don't use a distributor. The fine wire design of the center electrode helps maintain a consistent spark, and the iridium's high melting point makes it suitable for today's engines. You'll get a box of four, which is what you'll need for most 4-cylinder applications.
