1. Multi-ribs of insulator eliminate flashover.
2. Insulator made of 95% pure alumina, strong resistant to heat shock, great mechanic and electric features, super insulation.
3. Nickel-plated housing prevents oxidation and corrosion; heat-crimping process ensures absolute gas-tight fit.
4. Inner sealing with conductive glass ensures a fine conductivity and sealing.
5. Multi-layer gaskets are elastically strong, and reliable in sealing.
6. Copper core electrode prevents oxidation and corrosion, good electric and heat conductivity, long spark plug service life.
