Spark Plugs

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 conductivity 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, prolongs spark plug service life
