small gasoline engine

1. New ceramic insulator provides better insulation, heat dissipation, resistance again heat shock and mechanic failure. 2. Nickle-plated shell prevents oxidation and corrosion, electrical heat crimping process ensures reliable sealing. 3. Multi-ribs designed on the insulator can eliminate flashover 4. Resistor glass not only ensures conductivity and sealing but also provides protection from radio interference. 5. The centre electrode has a copper deeply inserted inside the nickle alloy tip, vastly improves heat dissipation and preventing dangerous overheating of the engine.
