What is the purpose of the trivalent metal plating?

The trivalent metal plating on these spark plugs provides superior resistance to corrosion and seizing. This helps ensure that the spark plugs can be easily installed and removed, even after extended periods in the engine.

How does the copper core benefit the spark plug?

The solid 98% pure copper core offers excellent heat dissipation and conductivity. This helps the spark plug maintain an optimal operating temperature, contributing to reliable performance and a wider heat range.

What does the triple gasket sealing do?

The triple gasket sealing is designed to prevent combustion gas from leaking past the spark plug. This ensures that the combustion process within the cylinder remains efficient and contained.

Product Details

The pure copper core in these NGK Standard spark plugs is key to their performance. It offers solid heat dissipation and conductivity, helping to keep the plug at its optimal operating temperature across a wide range of conditions. These are the same kind of plugs you'd find as original equipment on many engines, built with technology customers have trusted for decades.

NGK uses a high-grade alumina silicate ceramic for the insulator, which creates a strong barrier and helps with heat transfer. You'll also find trivalent metal plating on the shell, which is a nice touch for preventing corrosion and making installation or removal easier down the road. The triple gasket sealing is there to make sure combustion gases stay where they belong, inside the cylinder.

This box contains 10 spark plugs, making it a convenient way to get all the plugs you need for a multi-cylinder engine. They're built for a long life and consistent performance, so you can count on them to keep your engine running smoothly.
