E3 Automotive Spark Plugs with DiamondFIRE Technology have a patented side wire (ground electrode) configuration, which results in an increase in power output, fuel economy, and reduced emissions in all gasoline engines.

Energy -More pressure is created against the cylinder and more of the available fuel is put to work. Power is improved 3%-6% on average in typical operating ranges. Results may vary. Efficiency - Another benefit of E3?s faster flame propagation is less fuel is wasted, resulting in improved fuel efficiency. Lab and Dyno testing typically results in 3%-4% improved Brake Specific Fuel Consumption (BSFC). Results may vary. Ecology - E3?s more complete burn drastically reduces carbon emissions and carbon build up. E3 Automotive Spark Plugs come with a 5 Year/100,000 Mile Limited Warranty
