About this part

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.
