Ceramic insulator • The five rib design is used throughout the surface • This reduces voltage loss and prevents missed sparks • High-purity alumina is used • Good electrical insulation, durability and thermal conductivity • Chemically stable | ![]() | Terminal • To guarantee the credibility of spark plugs and the high voltage wire connection • Terminals adopt international standards for general size |
Nickel-plated plug body • Antioxidant • corrosion resistant • Electric heating riveting edge • Reliable sealing | With a resistance glass sealing material • Ensure the tightness and conductive • Make the spark plug is environmental protection product radio interference suppression | |
Captive outer sealing ring • Heat resistance, gives good hermeticity and low variation in heat Range | Copper cored center electrode • Compared to other manufacturers there is more copper with better thermal properties. | |
Inner seal | Ground electrode • Use of precious metals, more complete combustion, longer life |
