Details on 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-tipped center electrodes and platinum ground electrodes. This combination enhances spark stability and ignitability, which can contribute to smoother engine starts and better fuel combustion. The 96457 part number is a representative model within this line, designed to meet the ignition demands of multiple vehicle makes and models.

Technical Description and Specifications

This spark plug features a projected square platinum ground electrode tip that increases ignitability by providing a more focused spark area. Both the center and ground electrodes have copper cores, which improve electrical conductivity and heat dissipation. The center electrode tip is made of ruthenium, a material known for its hardness and resistance to wear, ensuring long service life. The spark plug has a resistance rating of 5000 ohms to reduce radio frequency interference. Its flat seat design and 14mm thread diameter with a 0.75 inch reach make it compatible with a variety of engines. The pre-gap size of 0.044 inches is factory set for optimal ignition performance.
