What Are Ruthenium Spark Plugs?

Ruthenium spark plugs are a type of spark plug that uses the metal ruthenium to enhance durability and improve ignition performance.

Spark plugs play a crucial role in an engine by igniting the air-fuel mixture in the combustion chamber, and the material used in the spark plug’s construction can significantly affect its performance.

Ruthenium is a metal that belongs to the platinum group and is known for its outstanding hardness and high melting point.

These properties make it an excellent choice for spark plug construction. When used in spark plugs, ruthenium can enhance durability, improve ignition performance, and provide better resistance to erosion compared to traditional materials like platinum or iridium.

This means engines equipped with ruthenium spark plugs may offer smoother running, improved fuel efficiency, and longer service intervals.
