NGK Standard spark plug is an OE-equivalent nickel-alloy replacement intended to restore dependable ignition for everyday engines. The alumina silicate ceramic insulator improves dielectric strength while a solid copper core enhances heat dissipation and conductivity. Triple gasket sealing prevents combustion gas leakage, corrugated ribs reduce flashover, and trivalent plating offers corrosion and anti-seize protection. Packaged as a box of ten, this shop pack supports maintenance needs with OE-style durability and easier installation and removal.
