NGK Multi-Ground Spark Plug Box of 4 (BKR6EK)

When it's time to replace your spark plugs, especially on vehicles like a BMW 318i or a Porsche 911 from the 90s, you want a part that's going to fire consistently. These NGK Multi-Ground spark plugs are designed to do just that. They offer reliable performance that's been trusted for decades, often as original equipment on many cars.

What sets these apart is the multi-ground electrode design. This setup helps improve ignition capabilities and is less sensitive to the increased voltage needs that can come with a slightly worn spark plug gap. The core is made of 98% pure copper, which is great for dissipating heat and conducting electricity effectively. Plus, the trivalent metal plating on the plug body helps prevent corrosion and seizing, making them easier to install and remove down the road. The insulator is made from a high-grade alumina silicate ceramic, which provides strength and good heat transfer, while triple seals keep combustion gases where they belong.

This box contains four plugs, which is a common quantity for many 4-cylinder engines, but always check your vehicle's specific needs. They are a solid option for maintaining your ignition system's health.
