The NGK Spark Plugs R6254E-105 Spark Plug is designed for dependable ignition performance in high-performance and demanding automotive applications. Manufactured by NGK Spark Plugs, this spark plug uses a copper-core center electrode to help transfer heat efficiently while supporting consistent spark delivery. Its construction is suited for engines that require reliable combustion, durable materials, and effective resistance to heat-related stress.
Trivalent metal plating helps provide superior corrosion resistance and anti-seizing properties, supporting easier service and long-term durability. The pure alumina silicate ceramic insulator delivers high strength and improved heat transfer, while triple seals help prevent leakage. Corrugated insulator ribs reduce the risk of flashover, helping maintain dependable ignition under demanding operating conditions.
