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 (US Patent # 6.495.948) 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. |

Truck Spark PlugsE3 truck spark plugs utilize the latest E3 technologies to help engines operate with more power by and creating more pressure against the cylinder and more available fuel is put to work. Get more power, better fuel efficiency and a faster/smoother acceleration. |
Small Engine Spark PlugsE3 small engine spark plugs have the same patented Edge-to-Edge DiamondFIRE ground electrode that has been proven to burn fuel more efficiently. Bring your L&G equipment to life, with quicker starts, more power, better fuel efficiency, and lower emissions. |
Power Sport Spark PlugsFor near perfect combustion, put in a set of E3 power sports spark plugs that are Born to Burn! Featuring the patented DiamondFIRE ground electrode, E3 power sport plugs provide more power, quicker starts, better fuel efficiency and lower emissions. |
Racing Spark PlugsE3's unique DiamondFIRE ground electrode helps to create more turbulence in the cylinder, and facilitate a faster flame growth. The result is more complete combustion, which results in more power and better consistency. E3 Racing Plugs cover a wide variety of Motorsports applications. |
Why Choose E3 Spark Plugs - DiamondFIRE Electrode
E3 combined their knowledge of performance spark plugs with the latest science to produce the unique DiamondFire ground electrode. This design mimics surface gap plugs used in rotary engines and reduces the flame kernel's travel time from the spark zone to the compressed gases in the engine's combustion chamber. The sharp edges produced by the DiamondFire design initiates strong electron migrations from the central electrode that improve the overall spark discharge. E3's multi-edge design is more efficient in creating a plasma channel to allow for a better flow of spark current, which burns compressed gases more completely and puts more of the available fuel to work in your engine.
