Standard Spark Plug is engineered for optimal performance and durability, featuring corrugated ribs to prevent flashover and ensure reliable operation. Its triple gasket-sealing process virtually eliminates combustion gas leakage, enhancing efficiency and longevity. The 99% highly pure alumina silicate insulator allows for longer insulator noses, reducing fouling and improving spark transfer for consistent ignition. With a 3-step trivalent-plating process utilizing silver chromate and zinc, this spark plug offers maximum corrosion resistance, ensuring it withstands harsh conditions over time. Designed with a gasket seat type, it provides a secure fit and superior heat transfer, making it an excellent choice for maintaining engine performance.
