NGK Standard Spark Plug Box of 4 (BR6ES)

Starting with a pure copper core, these NGK Standard spark plugs are built to handle heat effectively. The copper core offers solid conductivity and helps dissipate heat, which is crucial for consistent engine performance. This plug is designed as an OE equivalent, meaning it meets the same standards your vehicle came with from the factory, offering dependable ignition for a wide range of vehicles.

NGK uses a high-grade alumina silicate ceramic for the insulator, which creates a strong barrier that prevents electrical flashover and improves dielectric performance. For easier installation and to prevent seizing down the road, the exterior of the plug features trivalent metal plating. This plating gives it superior resistance to corrosion and seizing. The triple gasket sealing is also a notable detail, ensuring that combustion gases stay where they belong, inside the cylinder.

This box contains four BR6ES spark plugs, which is a common quantity for many 4-cylinder engines. They are a well-known and reliable choice for many classic cars, motorcycles, and even some industrial engines, offering a straightforward replacement for worn-out plugs.
