The Evolution of Spark Plugs

The Evolution of Spark Plugs

Without the spark plug, there would be no internal combustion engine.

Over the decades, ceramic improvements, electrode design, tip construction and advancements in metallurgy have dramatically improved the life and performance of these relatively low-priced engine components.

The original plugs – designed for low-speed and low-compression engines – had a life expectancy of far less than 1,000 miles, compared to today’s premium plugs made with high-quality precious metals such as platinum, iridium or ruthenium that are routinely expected to last for 100,000 miles or more.
