The NGK Standard spark plug is a proven OE-quality nickel alloy replacement trusted for decades for reliable starts and wide heat range performance. NGK uses high-grade alumina silicate ceramic for a strong insulator and triple gaskets to prevent combustion gas leakage. A solid 98% copper core aids heat dissipation and conductivity while trivalent metal plating helps prevent corrosion and seizing for easier installation and removal.
