Details on the Ruthenium HX High Ignitability Spark Plug Line

The Ruthenium HX High Ignitability Spark Plug line from NGK focuses on delivering improved ignition performance through advanced electrode materials and design. The use of a ruthenium tip on the center electrode enhances spark efficiency and durability, while the projected square platinum ground electrode supports high ignitability. This combination is intended to provide stable combustion and reliable starts in compatible vehicles.

Technical Description and Features

This NGK spark plug features a copper core in both the center and ground electrodes, which promotes excellent electrical conductivity and heat dissipation. The projected square platinum ground electrode tip is designed to improve ignitability, contributing to efficient combustion. The spark plug’s pre-gap is set at 0.032 inches, ensuring optimal spark gap for ignition. Its flat seat and 12mm thread diameter make it suitable for specific Hyundai and Kia models, including the Accent, Forte Koup, Rio, Soul, and Veloster. The non-removable nut terminal type provides a secure electrical connection, and the heat range of 6 aligns with the thermal requirements of these vehicles.
