NGK Traditional Spark Plug Box of 10 (BPR6FS)

The 98% pure copper core in these NGK 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. This is important because a plug that runs too hot can cause pre-ignition, and one that runs too cool can lead to fouling.

NGK builds these standard plugs with a high-grade alumina silicate ceramic insulator. This material is known for its strength and ability to transfer heat effectively, which helps prevent electrical breakdown. You'll also find a triple gasket sealing system here, designed to keep combustion gases from leaking out of the cylinder. For easier installation and removal, especially if the engine has seen a lot of miles, the trivalent metal plating on the shell provides excellent resistance to corrosion and seizing.

This is a box of 10 plugs, making it a convenient choice if you're working on an engine that requires multiple spark plugs. They're built for long life and dependable performance, just what you'd expect from a company like NGK.
