About the Ruthenium HX High Ignitability Spark Plug Line

The NGK Ruthenium HX High Ignitability Spark Plug line focuses on delivering improved ignition performance through the use of ruthenium, a durable and conductive metal, on the center electrode tip. This design 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 vehicles requiring reliable secondary ignition components.

Technical Details and Compatibility

This spark plug features a copper core in both the center and ground electrodes, which helps maintain excellent electrical conductivity and heat dissipation. The single projected square platinum ground electrode is designed to provide a stable spark while reducing electrode wear. With a pre-gap size of 0.044 inches and a tapered seat, the NGK 97100 spark plug ensures proper fit and optimal combustion chamber sealing.

Compatible with a wide range of GM vehicles, including Buick LaCrosse, Chevrolet Camaro, GMC Sierra 1500, Oldsmobile Cutlass Supreme, Pontiac Grand Prix, and Saturn Vue, this spark plug meets the specific ignition requirements of these models.
