NGK Laser Iridium Spark Plug (ILTR6F9)

You're getting a box of four NGK Laser Iridium spark plugs, part number ILTR6F9. These are designed as a direct replacement for your 2012 Ford Focus, ensuring a proper fit and function. They're built to give you a good balance of performance and how long they last.

The center electrode on these plugs uses an iridium alloy, which is known for being very durable and maintaining a stable spark. This helps with consistent engine operation. The insulator is made from pure alumina silicate ceramic, which is strong and helps manage heat effectively. Plus, they have a trivalent metal plating to help prevent corrosion and make them easier to remove later on.

These NGK plugs are a solid option if your Focus originally came with fine wire iridium plugs. The copper core helps pull heat away from the firing tip, and triple seals are used to prevent any leaks.
