NGK Laser Iridium Spark Plug (ILZKAR8J8SY)

The center electrode on these NGK Laser Iridium spark plugs is tipped with an iridium alloy, which is about six times harder than platinum. This makes them really durable and helps maintain a consistent, stable spark over their lifespan. They're built to be a direct replacement for the original plugs in your 2017-2020 Honda Civic, so you know they'll fit right and perform as expected.

NGK uses a pure alumina silicate ceramic insulator here, which is strong and helps transfer heat away from the plug effectively. This, along with the 98 percent pure copper core, helps prevent the plug from overheating. For vehicles with distributorless ignition systems, you'll also find a platinum pad on the ground electrode, which helps ensure even wear. The trivalent metal plating on the threads is a nice touch, helping to prevent corrosion and making them easier to remove down the road.

This set comes with four plugs, which is exactly what you'll need for your Civic. They're a solid option if your original plugs were also fine wire iridium type.
