Specification:

(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 gasket is elastically strong,and reliable in sealing.

(6)copper core electrode prevents oxidation and corrosion,good electric and heat conductivity,long spark plug service life.
