NGK Standard Spark Plug Box of 1 (AR6FS)

The pure copper core in this NGK spark plug offers solid heat dissipation and conductivity, helping to keep your engine running smoothly. This plug is built with a high-grade alumina silicate ceramic insulator that creates a strong barrier for optimal dielectric performance, and it uses triple gasket sealing to prevent combustion gas leakage. It's a well-known OE cornerstone that customers have relied on for decades, offering dependable performance for a wide range of vehicles.

NGK treats these standard plugs with a trivalent metal plating. This isn't just for looks; it delivers superior anti-corrosion and anti-seizing properties, which means it's easier to install and remove down the road. The corrugated ribs on the insulator help prevent flashover, ensuring a clean spark. This plug is designed for longer life and consistent performance, making it a solid choice for many applications.
