NGK Copper Core Spark Plug Box of 4 (BKUR6ET-10)

The solid 98% pure copper core in these NGK spark plugs is key to their performance. It offers superior heat dissipation and conductivity, helping to maintain optimal engine temperatures across a wide range of operating conditions. These are the same kind of reliable, OE-quality plugs that have been a staple for decades, designed specifically for original equipment applications.

You'll find the trivalent metal plating on the threads is a practical touch, offering excellent resistance to corrosion and seizing. This makes installation and later removal much easier, a detail any mechanic appreciates. The high-grade alumina silicate ceramic insulator is strong and provides excellent dielectric performance, while triple gasket seals prevent any combustion gas leaks. This well-built design ensures long life and consistent performance for your engine.

This set comes with four spark plugs, fitting a wide variety of vehicles including many Audi 100, A4, and A6 models, as well as the Volkswagen Beetle and Golf. They are a solid option for maintaining your ignition system's health.
