E3 Spark Plugs are the product of years of fundamental research in the combustion field. The unique patented electrode configuration of these new E3 spark plugs 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 all gasoline engines.

Great plugs!

Summit RacingSummit Racing Verified Purchase

This is my second set of E3s. The first set lasted for over the full 5 year warranty. If the advertised spark pattern is true, bigger spark, better burn. However, NOT for multi-spark discharge systems...
