NGK Laser Iridium Spark Plug Box of 4 (IZFR6J)

NGK Laser Iridium spark plugs are a solid option when you need to replace your worn-out plugs. These are built to meet or exceed the original equipment specifications for your vehicle, meaning they'll fit right and perform as expected. The center electrode uses an iridium alloy, which is a very hard material that helps the plug last much longer than standard platinum plugs. This means you get a stable spark for a long time, helping your engine run smoothly and efficiently.

You'll also find a platinum pad on the ground electrode, which helps it wear evenly, especially in modern ignition systems. The ceramic insulator is made from pure alumina silicate, which is strong and helps manage heat effectively. Plus, the metal plating on the outside helps prevent corrosion and makes them easier to remove later on. These plugs are designed to handle the demands of today's engines, providing reliable starts and consistent performance.
