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.

Automotive Spark Plugs

E3 automotive spark plugs utilize the latest E3 technologies to help engines operate more efficiently by burning fuel more completely. Get more power, better fuel efficiency and a faster/smoother acceleration. E3 Automotive plugs come with a 5 Year/ 100,000 Mile Warranty.

Small Engine Spark Plugs

E3 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. E3 Lawn and Garden plugs come with a limited Lifetime Guarantee.

Power Sport Spark Plugs

For 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. E3 Power Sport plugs offer a defect warranty for the 90 days.

Racing Spark Plugs

E3'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.

User questions & answers

Question:	Is this 6r12, if so why does it not say so
Answer:	I never trust "Pre-gapped"; always do your own checking. Better safe than sorry!
Question:	Do you get 1 or 2 spark plugs in this price
Answer:	Product description says Pack of 1.
Question:	Should I gap to my owners manual spec or are they designed to work with the smaller pre-gap they came with
Answer:	Your question is out of my reach but I can tell you that on my Hyundai Sonata 2002 this plugs just revived it to a near new condition . I've got power I didn't know it had.
Question:	They come pre gapped to what spec
Answer:	I received my NGK plugs with a .042 gap. My Toyota Corolla Owners manual say's .043 for a gap setting. Advance AutoParts.com has post for this plug a gap setting of .044. Since the settings were not correct and technically the plugs should have came with the correct gap Amazon made good on the purchase. So now I need to possibly reorder. Ebay has these plugs, 4 for 14.99. Maybe that's why.
