Brand Information

E3 Spark Plugs are the product of years of fundamental research in the combustion field. This research was conducted at our company laboratories, at first, and then refined at two leading engineering universities by top professors in the field of combustion and engine dynamics.

It was through key advances in computer-aided data acquisition that our company was able to discover subtle but critical differences in spark plug electrode function. Using the world's most advanced (and proprietary) engine combustion dynamometer, our engineers and researchers were able to develop an electrode configuration that increases the amount of combustion pressure created during each power stroke of an engine, which results in a marked increase in power output, fuel economy, and reduced emissions in gasoline engines.
