E3 Spark Plugs

4.64 out of 5 stars 706 Customer Reviews

Energy, efficiency, and ecology--that's the E3 equation! The unique patented electrode configuration of the E3 spark plugs increases the amount of combustion pressure created during each power stroke of an engine. This, of course, results in a marked increase in power output, fuel economy, and reduced emissions in all gasoline engines.
