E3 Spark Plugs

The DiamondFIRE ground electrode configuration 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.

Smoother Acceleration and Idle – The faster flame propagation initiated by the Patented DiamondFIRE ground electrode results in a more complete burn of the fuel/air mixture.

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.

Why Do You Need E3 Spark Plugs?

As the designated catalyst for the ignition of fuel in gasoline powered cars, trucks, motorcycles and small engines, spark plugs are a small, but constant factor in the workings of the vast majority of motorists on the road. What these motorists may not know is that their choice of spark plug could play a significant role in reducing the level of greenhouse gases that their vehicles give off, as well as increasing overall fuel economy and potential power output. This is where E3 Spark Plug's DiamondFire technology comes in.

Key Features

Nickel Plated Terminal End- Corrosion protection at the main contact point with your engine's ignition system.

Projected Insulator Tip- We have the deepest projections in the Industry, promoting better spark-zone refreshing between power strokes, without any negative side effects.

Spark Gaps Tailored to Your Engine- Unlike other 'premium' spark plugs that use a 'one size fits all' gap policy, E3 Spark Plugs have carefully optimized spark gaps chosen to maximize performance for each application.

E3 Spark Plug's patented ground electrode design provides for more efficient burning of your vehicle's air/fuel vapor, leading to more pressure in the cylinder. These improvements are measurable, and confirmed as compared to the designs found in existing spark plugs. The DiamondFIRE electrode projects the spark further into the combustion chamber, bringing it closer to the most robust air/fuel mixture. The initial combustion wave leaves the spark area at supersonic speeds, and the elevated edge provides a chimney effect so the next round of air/fuel mixture gets into the spark zone more easily.

The E3 ground electrode design forces edge-to-edge spark discharge, which is the best way to get a spark to leave a surface. Sharp edges are better at initiating electron migrations, and these accelerated electrons collide with matter inside the spark zone to release additional electrons. This design ensures that the whole population of electrons works to create a plasma channel through which the spark current flows more easily, resulting in an increase in both power output and fuel economy, while reducing emissions in gasoline engines and the build-up of carbon deposits on engine surfaces.

E3 Power Sports spark plugs are a clear breakthrough in spark plug technology. Developed by researchers from leading engineering universities, E3's patented electrode design allows for a better spark, and resulting more complete flame kernal and flame front extending off the electrode, producing better overall localized pressure inside your boat, jetski, ATV or snowmobile's engine's cylinder(s). This in turn leads to the fuel/air mixture injected into the cylinder being more cleanly consumed, lessening the level of greenhouse gases emitted, increasing energy efficiency and generating more horsepower. .caption { font-family: Verdana, Helvetica neue, Arial, serif; font-size: 10px; font-weight: bold; font-style: italic; } ul.indent { list-style: inside disc; text-indent: -15px; } table.callout { font-family: verdana; font-size: 11px; line-height: 1. 3em; } td.vgoverview { height: 125px; background: #9DC4D8 url(https://images-na.ssl-images-amazon.com/images/G/01/electronics/detail-page/callout-bg.png) repeat-x; border-left: 1px solid #999999; border-right: 1px solid #999999; padding-left: 20px; padding-right: 20px; padding-bottom: 10px; width: 250px; font-family: verdana; font-size: 12px; }

As the designated catalyst for the ignition of fuel in gasoline power sport vehicle engines, spark plugs are a small, but constant factor in the workings of the vast majority of snowmobiles, ATVs, jetskis, boats and vehicles with similar performance needs. What owners of these vehicles may not realize is that their choice of spark plug could play a significant role in reducing the level of greenhouse gases that their engines give off, as well as increasing their overall fuel economy and potential power output. This is where E3 Spark Plug's DiamondFire technology comes in.

DiamondFire Technology
For the last 100 years, the only real advance in consumer spark plug technology has been to develop ways to make them cheaper. E3 Spark Plug's DiamondFire technology changes all of that through an improved electrode design that provides for more efficient burning of your engine's air/fuel vapor, leading to more pressure in the cylinder. These improvements are measurable, confirmed and based on the following design elements found in existing performance spark plugs.

First, the DiamondFire electrode directs the flame kernel to the piston more directly, reducing the travel time from the spark zone to the end gases via the open section at the top of the electrode. Given the short time available to get combustion started, the faster you can get the flame to the piston, the better. Second, the physical features of the electrode project further forward into the combustion chamber. This brings the spark zone closer to areas of probable "good" air/fuel mixture and also creates beneficial "micro-aerodynamics" within the spark zone. The initial combustion wave leaves the spark area at supersonic speeds above Mach 1, and the elevated edge provides a kind of chimney effect so the next round of air/fuel mixture gets into the spark zone more easily. Finally, the E3 electrode design features forced edge-to-edge spark discharge, which is the best way to get a spark to leave a surface. This improves upon the phenomena that drove race car drivers to "cut back" ordinary electrode spark plugs in order to improve the spark discharge. The spark itself occurs only when an avalanche of electrons migrates from the two electrodes (anode to cathode). Sharp edges are better at initiating electron migrations, and these accelerated electrons collide with matter inside the spark zone to release additional electrons. This design ensures that the whole population of electrons works to create a plasma channel through which the spark current flows more easily, resulting in an increase in both power output and fuel economy, while reducing emissions in gasoline engines and the build up of carbon deposits on engine surfaces.

Key Features:

  • DiamondFire electrode technology that creates a superior spark and resulting flame front extending further into the cylinder, producing more localized pressure.
