Spark Plug Specification:
Size: M14×1.25mm, Reach:19mm, Hex:16mm, Gap:0.8mm
1)..Multi-ribs designed on the insulator can eliminate flashover
2)..New ceramic insulator provides better insulation, heat dissipation,
     resistance against heat shock and mechanical failure
3)..Nickel-plated shell prevents oxidation and corrosion, electrical heat
     crimping process ensures reliable sealing
4)..Resistor glass not only ensures conductivity and sealing but also
     provides protection from radio interference
5)..The center electrode has a copper deeply inserted inside the nickel
     alloy tip, vastly improves heat dissipation and preventing dangerous
     overheating of the engine
