NGK Laser Iridium Spark Plug Box of 4 (TR6AP-13)

When it's time to replace the spark plugs on your 2006-2010 Ford Focus, you want a part that's going to keep that engine running smoothly. These NGK Laser Iridium spark plugs are a solid choice for maintaining your vehicle's performance. They're built with a fine wire center electrode, which is key for ensuring a consistent and stable spark, something you really want for reliable ignition.

What sets these NGK plugs apart is the iridium alloy used in the center electrode. Iridium has a very high melting point, making it durable and able to handle the demands of modern engines. The pure alumina silicate ceramic insulator helps with heat transfer, preventing the plug from overheating, while the trivalent metal plating offers good protection against corrosion and seizing, making them easier to remove next time. Plus, the copper core helps pull heat away from the firing tip.

This set comes with four plugs, which is exactly what you need for your Focus. They're designed as a direct replacement for your original equipment, so they should fit right in without any issues.
