What is the advantage of multi-ground electrodes?

Multi-ground electrodes help improve ignition capabilities. They are also less sensitive to increased voltage requirements that can occur as the spark plug gap grows over time.

Does this spark plug come with anti-seize pre-applied?

The spark plug features trivalent metal plating, which delivers superior anti-corrosion and anti-seizing properties, ensuring ease of installation and removal. It is not pre-coated with a separate anti-seize compound.
