NGK Standard Spark Plug (BR8ET)

NGK is known for making reliable ignition parts that many manufacturers trust for their vehicles. For your 1980 Mazda RX-7, these NGK Standard spark plugs are a solid choice, offering proven OE quality and dependable performance. They are designed to be a direct replacement, making the job straightforward.

These plugs feature a pure alumina silicate ceramic insulator, which is strong and helps with heat transfer. The copper core inside is great for dissipating heat and conducting electricity, and the trivalent metal plating on the outside helps prevent corrosion and seizing, so they're easier to install and remove later. NGK also uses triple seals to make sure combustion gases don't leak out.

This set comes with four plugs, which is exactly what you'll need for your RX-7. They are built for a long service life and consistent performance.
