(1)   New ceramic insulator provides better insulation, heat dissipation, resistance again heat shock and mechanic failure.

(2)   Multi-ribs designed on the insulator can eliminate flashover.

(3)   Nickle-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 centre electrode has a copper deeply inserted inside the nickle alloy tip, vastly improves heat dissipation and preventing dangerous overheating of the engine.

(6)   Larger space between insulator nose and metal shell educes fouling and misfiring and keeps plug cleaner.
