E3 Spark Plug E3.72 Automotive Spark Plug, Pack of 1

The E3 advanced DiamondFire design actually increases combustion pressure in the engine. Faster flame speed and improvements in the direction of the flame front result in a marked and proven, increase in power output, fuel economy, and reduced emissions in gasoline engines. E3 has verified this using the most sophisticated testing equipment available today. E3 is dedicated to reducing greenhouse gas emissions and global warming by reducing fuel consumption. Their advanced DiamondFire electrode design burns fuel more efficiently and completely, increasing mileage and drastically cutting toxic emissions. E3 has taken the best features from traditional spark plugs, such as cut-back ground electrodes and surface gaps, and combined them to create a new ground electrode design. Surface gap plugs present the flame kernel to the piston (or rotor) more directly, reducing the travel time from the spark to the combustion gases (although this difference is only measurable in hundred-thousands of a second, at 5000 RPM, they can add up). This avoids the "doughnut" shaped flame front created by standard spark plug electrodes. This is achieved in the E3 design through the open section at the top of the ground electrode. E3 spark plugs combine the benefits of additional sharp electrode edges with a cut-back electrode design used on some racing spark plugs. The increase of available edge-to-edge surface area encourages a more rapid spark discharge while also reducing quenching and shadowing. The two legs that support the special geometryof E3's powersports plug ground electrode aid in heat dissipation for longer electrode life. The center electrode on E3 spark plugs is created from nickel alloy with a copper center core for both improved conductivity as well as heat dissipation.

Quicker starts as a result of reduced carbon build up Better fuel economy as a result of all the fuel being put to work during each combustion cycle Dramatically reduces toxic emission through a more complete combustion process Increased horsepower
