Spark Plug

 95% pure alumina insulator;
Multi-ribbed insulator eliminates flashover;
Inner sealing with conductive glass ensures a fine conductivity and sealing;
Multilayer gaskets are elasticly strong, and reliable in sealing;
Copper core electrode vastly improves heat dissipation and prevents overheating of the engine;
Nickel-plated housing prevents oxidation and corrosion, electrical heat crimping process ensures reliable sealing
