NGK Laser Iridium Spark Plug Box of 4 (SILZKR6D8E)

NGK is well-known for making reliable ignition components, and their Laser Iridium spark plugs are a prime example of that. If you're working on your 2014-2016 Kia Forte Koup and need to replace the spark plugs, these are built to match the original equipment specifications, offering a good balance of performance and how long they last.

These plugs feature a fine wire iridium center electrode, which is significantly harder than platinum and helps maintain a stable spark. The pure alumina silicate ceramic insulator is strong and transfers heat well, while the trivalent metal plating on the body helps prevent corrosion and seizing, making them easier to remove next time. The ground electrode also has a platinum pad, which helps it wear evenly, especially in modern ignition systems. Plus, the copper core inside helps keep the plug from getting too hot.

This set comes with four spark plugs, enough for a typical four-cylinder engine. They are designed to be a direct replacement for your original plugs, so installation should be straightforward.
