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