Improve fuel economy by simply changing your spark plugs! Only E3® Spark Plugs have an open diamond-shaped architecture electrode that provides a more complete combustion of the air/fuel mixture in the cylinder. Improved combustion increases fuel economy, lowers CO and CO2 emissions and provides longer “like new” engine performance. Typical horsepower gains are 4-6%, depending upon engine class size. E3 spark plugs are now readily available at most automotive and hardware stores. For more information, visit www.e3sparkplugs.com.
