NGK Laser Iridium Spark Plug Box of 4 (ITR5H13)

You're getting a box of four NGK Laser Iridium spark plugs, part number ITR5H13. These are designed to be a direct replacement for your vehicle's original spark plugs, offering a good balance of performance and how long they last. They're built with a pure alumina silicate ceramic insulator that helps with heat transfer and provides solid strength. The center electrode is made from an iridium alloy, which is much harder than platinum and helps ensure a consistent spark over time. For vehicles with distributorless ignition systems, the ground electrode has a platinum pad to help it wear evenly.

The pure copper core inside these plugs helps prevent them from getting too hot, and the trivalent metal plating on the outside helps resist corrosion and makes them easier to remove later on. NGK uses triple seals to make sure there are no leaks. These are a solid option if your vehicle originally came with fine wire iridium alloy spark plugs.
