About the Ruthenium HX High Ignitability Spark Plug Line

The Ruthenium HX High Ignitability Spark Plug line from NGK is designed to provide improved ignition performance through the use of ruthenium, a durable and conductive metal, on the center electrode tip. This technology enhances spark efficiency and contributes to better fuel combustion. The projected square platinum ground electrode further supports high ignitability, making this product line suitable for modern engines requiring precise ignition control.
