NGK Standard Spark Plug Box of 4 (LKR6E-9N)

This product is a box of four NGK Standard spark plugs, part number 90410, with the model number LKR6E-9N. These are a proven OE (Original Equipment) replacement, meaning they are built to the same standards as the plugs that came with your vehicle from the factory. They use a high-grade alumina silicate ceramic insulator, which is strong and helps with heat transfer. The pure copper core inside the plug helps dissipate heat and offers good conductivity, while the triple gasket sealing is there to prevent any combustion gases from leaking out.

You'll find the trivalent metal plating on these plugs is notable for resisting corrosion and preventing them from seizing up, making installation and later removal much easier. The corrugated ribs on the insulator help prevent flashover, which is when electricity jumps to the wrong place instead of firing the spark plug. NGK has been a trusted name in ignition components for decades, and these standard plugs are built for a longer life and consistent performance.
