NGK Copper Core Spark Plug Box of 4 (BCPR6ES-11)

The solid 98% pure copper core in these NGK spark plugs helps dissipate heat effectively, which is crucial for maintaining consistent performance. These are NGK Standard spark plugs, the same kind you'd find as original equipment on many vehicles, offering reliable performance that customers have trusted for years. They are built with a high-grade alumina silicate ceramic insulator for strength and dielectric performance, and feature triple gasket sealing to prevent any combustion gas leaks.

NGK treats these plugs with trivalent metal plating, giving them superior resistance to corrosion and seizing. This means they'll be easier to install and remove down the road, which is always a nice bonus. The corrugated ribs on the insulator help prevent flashover, ensuring a strong spark. This set comes with four plugs, making it a convenient option for many 4-cylinder engines or other applications that require this specific plug type.
