Product Description

The NGK 2-LKAR8A-9 (4786) is a standard nickel alloy spark plug engineered for reliable ignition performance. Designed for original equipment applications, this plug features a 98 percent pure copper core, which provides superior heat dissipation and electrical conductivity across a wide operating temperature range. The construction utilizes high-grade alumina silicate ceramic for the insulator to ensure optimal dielectric performance and strength. To prevent combustion gas leakage, the spark plug is built with triple gasket sealing. The shell is finished with trivalent metal plating to provide excellent anti-corrosion and anti-seizing properties, facilitating easier installation and removal. This spark plug has a thread diameter of 12mm, a reach of 26.5mm, and a 14mm hex size. It is a resistor-type plug with a 5k Ohm resistance value. Please verify fitment for your specific application before purchasing.
