Product Details

When it's time to replace your spark plugs, especially on vehicles like a Honda Civic, a Toyota Camry, or a Ford Escort from the 90s and early 2000s, NGK's traditional spark plugs are a solid choice. These are the same kind of plugs you'd find as original equipment, meaning they're built to meet the specific needs of your engine for reliable performance and smooth running.

What makes these plugs stand out is their construction. They feature a pure copper core, which is excellent at dissipating heat away from the plug tip, helping to keep things running at the right temperature. The insulator is made from high-grade alumina silicate ceramic, giving it strength and good dielectric properties. Plus, the metal plating on the outside isn't just for looks; it's designed to resist corrosion and seizing, making them easier to install and remove down the road. They also use triple seals to make sure combustion gases stay where they belong.

NGK has been making these types of plugs for a long time, and they're known for lasting a good while and performing consistently. This box includes four plugs, which is what many common four-cylinder engines need. Just make sure to check your vehicle's specific requirements to confirm this is the correct plug for your application.
