Our spark plugs are very cost effective, they not only have the competitive price but also have well performance: 1, The multi-channel umbrella edge on the insulators can effectively preventing the surface flashover, The inulators, making of 95 high-alumina ceramics are of heat shock, good mechanical-electrical performance and reliable insulation. 2, Nickel-plated shell surface can be anti-oxidation, corrosion-resistant.we use electric heating riveting edge, the sealing performance are very reliable, the inner seal is conductor glass sealant , conductive and seal are all of excellent performance. 3, we use stacked sealing gaskets, it is of good elasticity, high spring, anti falling, and reliable seal, the center electrode using nickel-copper composite (copper core) electrodes, the products are of good thermal conductivity and electrical conductivity, anti high temperature, anti-oxidation, corrosion resistance, and long life-span.
