Product description

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 geometry of E3's power sports 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.

• Near elimination of performance inhibiting carbon deposits, dramatically longer plug life and a 5-year/100,000 mile limited warranty
• DiamondFire electrode technology that creates a superior spark and resulting flame front extending further into the cylinder, producing more localized pressure
• Significant potential power increase: > 6percent to 12percent (depending on engine class)
• Significant potential fuel efficiency improvement: > 4percent to 13percent (depending on engine class)
• Drastic potential emissions reduction when used in 2 and 4-stroke engines (after 50 hours): 58percent CO emissions reduction, 42percent hydrocarbon reduction
• Near elimination of performance inhibiting carbon deposits, dramatically longer plug life and a 5-year/100,000 mile limited warranty
• Diamond Fire electrode technology that creates a superior spark and resulting flame front extending further into the cylinder, producing more localized pressure

User questions & answers

Question:	Are the e3 spark plugs approved by ford motor company as far as ford warranty is concerned
Answer:	China
Question:	How many per pack ? Ty
Answer:	It should it works for my plug in Chevy volt. Love my charger
Question:	Amazon warehouse has e3.74 listed as "used - very good". have they actually been used or are they just damaged packaging or returns
Answer:	I bought the 40 amp charger which requires a NEMA 6-50 socket to be installed. It should be installed by a professional electrician and may run you between 400.00 and 600.00 dollars to install depending on where you live. My cost was $400.00.
Question:	will these fit a 2016 mustang gt
Answer:	Yes, this will work but it's a bit overkill. A 32 amp station will maximize the charge rate of your eGolf (at ~20 miles of range per hour of charge). We have found the PowerCharge Energy Series station to be a better value and more reliable. https://www.amazon.com/PowerCharge-Electric-Vehicle-Charging-Installation/dp/B07FY1181C/ref=sr_1_1?s=automotive&ie=UTF8&qid=1543783020&sr=1-1&keywords=powercharge

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.

User questions & answers

Question:	Will this plug work in a 2001 Mazda Tribute
Answer:	Depends. These plugs from my understanding are a few temps cooler-- which helps my chipped mk5 turbo. Also these plugs are .44, my mk5 runs best @ .32 gapping--so if you are going to re-gap BE CAREFUL...
Question:	Will this plug fit a 6.5hp predator motor
Answer:	These plugs are for real. They will give more performance at all rpm levels.
Question:	Will this fit on a predator 420cc
Answer:	My practice is to ALWAYS check the gap. Be aware that the center electrode is small and somewhat delicate. My last set was in my VW 2.0 turbo for 15K mi. and the gap grew .007-.008". So next time I might try a different plug. Car was running good even with the increased gap and old plug color was good. It appears some VW turbo owners like NGK iridium and I have used Autolite Iridium also.
Question:	Does this fit predator 212cc
Answer:	It indicated it would fit in Toyota engines without adjusting the gap, but the Amazon part finder does an excellent job of indicating fit. I would rely on that rather than the instructions.

Product description

The exceptional performance of the E3 spark plug starts with the unique open architecture of the E3 electrode. The design forces air gap discharges, creates the preferred edge-to-edge spark path, allows free replenishment of the spark zone with a fresh fuel/air charge, and exposes the flame front more directly to the piston head than other plug designs. Sparks naturally follow edge-paths as they leave an object. The E3 design presents multiple sharp edges to the center electrode. Sparks flow between these edges at lower voltages, facilitating easier discharge than standard designs. By forcing air sparks, the resistance to fouling is greatly increased in the E3 spark plug. This lowers the self-cleaning temperature of the spark plug, allowing colder heat ranges to be used if desired. E3's distinctive spark plug design has proven, in testing in a range of engines, to simultaneously increase engine power output, reduce gasoline consumption, decrease hydrocarbon and carbon monoxide emissions from the engine and materially extend the life of the spark plug.

• Near elimination of performance inhibiting carbon deposits, dramatically longer plug life and a 5-year/100, 000 mile limited
• Diamond fire electrode technology that creates a superior spark and resulting flame front extending further into the cylinder, producing more localized pressure
• Significant potential power increase: > 6% to 12% (depending on engine class)

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.

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.

User questions & answers

Question:	Does this fit a 2002 bmw 330i
Answer:	Check the E3 website. Look up which plug they recommend for your vehicle, then order that one... amazon is cheaper than their website by a little bit.
Question:	i will they fit
Answer:	I have no idea and I will never trust this company again. I ran the plugs they recommended and the plating burned off. 1000 miles and they were completely worthless Worst plugs I've used in 43 years.
Question:	Are these spark plugs pre-gapped
Answer:	Don't know about your bike They worked on my 2001 Electra Glide Ultra Classic. Didn't notice any difference in performance. Going to try Screaming Eagle plugs.
Question:	I have a 2005 bmw 330xi. do i have to gap these spark plugs
Answer:	Yes. The standard engine for a 2005 Fatboy is the 1450 and as long as you have this engine the E3.36 is the proper plug for your bike, Trust me you will not regret spending the money for them. They are worth every penny. Your bike will definitely show you the difference. Ride hard or stay home!!!
