Product Details

NGK Standard spark plugs, like this BR8ES model, are a popular choice for many vehicles that rely on proven OE technology. They offer dependable performance and are built with a focus on durability. This particular plug is sold individually but comes in a box of four, making it easy to get exactly what you need for your application.

Inside this spark plug, you'll find a solid 98% pure copper core. This copper core is key because it helps dissipate heat effectively and conducts electricity well, which is important for consistent ignition. The insulator is made from high-grade alumina silicate ceramic, which provides strong dielectric performance and helps prevent flashover. NGK also uses trivalent metal plating on the exterior, which gives it good resistance to corrosion and makes it easier to install and remove without seizing.

These plugs are designed for long life and consistent performance. The triple gasket sealing is a notable detail that helps prevent any combustion gases from leaking out, ensuring the plug functions as intended. If you're working on a variety of vehicles, from older ATVs to personal watercraft, these NGK plugs are a solid option.
