The unique patented ground electrode configuration increases the amount of combustion pressure created during each power stroke of the engine, which results in a marked increase in power output, fuel economy, and reduced emissions in all gasoline engines. E3's DiamondFire edge to edge ground electrode provides maximum performance with increased efficiency and a faster more complete burn.Our company was formed to find a better design that would provide E3 customers with performance advantages such as increased power, improved fuel efficiency, and a reduction in hazardous engine emissions that can contribute to global warming. With decades of experience in spark plug engineering and the automotive aftermarket, the principals of E3 Spark Plugs realized that the key to producing a better spark plug did not lie in the use of fancy metals, such as iridium or platinum. Instead, it would require an entirely new approach in the design of the plug's electrode to improve the ignition of raw fuel inside the engine's combustion area. The first step would be to get rid of the antiquated J-wire electrode. This would allow the flame kernel to move directly toward the unburned air/fuel mixture. E3's initial research started in its own laboratories and led to the testing of new designs at two leading engineering universities. After investing in years of research and assisted by top professors in the field of combustion and engine dynamics, the DiamondFire ground electrode was developed as a better way to ignite the fuel-air mixture inside the engine's cylinder. Since this advanced design increased the combustion pressure inside the engine before raw fuel was exhausted, they had discovered a better way to control the burn. A faster flame speed and improvements in directing the spark inside the combustion area resulted in a marked (and proven) increase in power output, fuel efficiency, and reduced emissions for gasoline-powered engines. These results were validated using the some of the most sophisticated testing equipment available. Over and over again, the new plug burned fuel more efficiently, improved power response, and cut toxic emissions. Today, E3 remains dedicated to reducing greenhouse gas emissions by limiting the amount of unburned fuel.

Performance

Fuel

[This review was collected as part of a promotion.] I recently purchased E3 spark plugs for my 2014 3.7L Mustang and noticed an immediate improvement in running and mileage so I also replaced the plugs in my 1977 Pontiac CanAm 455 V8 and the difference in cold start, idle and at speed was remarkable. Highly recommended!

E3 spark plugs are excellent.

e3sparkplugs.com

[This review was collected as part of a promotion.] I use E3 plugs and all my vehicles. Best plugs on the market. They improved gas mileage, and they lasted longer than any other plug that I've had.

In my opinion, best plugs on the market

Trying to solve a Ford Ecoboost misfire problem. The E3's definitely have improved the performance and mitigated the misfires to some extent.

Misfire improvement

[This review was collected as part of a promotion.] Anytime I am putting plugs in an engine of any kind, I always check to see if there is an E3 plug available.

If there is a E3 plug for the engine, I use it

[This review was collected as part of a promotion.] I have always seen E3 spark plugs on NHRA racing and decided to try them recently  on my Mercury four stroke. Upon first start up I noticed a quick start up and the engine idle was incredibly smooth! When I accelerated the boat got on plane immediately and was running strong! I normally after using the boat Tuesday through Friday went to fill the fas tank and it only took half  of a tank over  the normal almost empty by Friday? I was so impressed  I just now installed E3 spark plugs in my 2003 Chevrolet Trailblazer with a 4.2 engine with a 152,000 miles inwhich this engine had a rough idle and is known for this issue.  I am on my third week and the rough idle is now smooth. My fuel consumption as my outboard engine was now using a lot less fuel, almost as the boat. After the same week of towing my boat I used to go through a tank of fuel. I'm now at half the fuel consumption I was using! Thank you E3 for such a wonderful designed spark plug that has helped a retired guy keep doing what he loves with the fuel cost now half of what it was costing! God Bless you all!!!

Outstanding fuel economy and performance

[This review was collected as part of a promotion.] I heard about these plugs from a friend ordered them for my  STX with a coyote couldn't believe the difference they made in fuel efficiency and power so I ordered some from my 13 Mustang GT same positive outcome love these plugs!!

The only plugs for me!!

I have been using E3 plugs in my small engines for years, now I will be using them in my car and I can't wait to see how they perform.

Stepping up to automotive use

[This review was collected as part of a promotion.] Best Spark plugs ive ever bought and they perform better than i expected. Definitely a lifetime customer.

2016 Ford Fusion

These E3 plugs replaced OEM iridium in a Ford Fusion hybrid. E3 plugs have been in engine a month. Observed increased acceleration and quieter engine. Pleased with performance gains.

Good OEM replacements

[This review was collected as part of a promotion.] My gas milage had decreased considerable over the past year and after replacing my original factory sparkplugs with E3.74 plugs, my mileage went from about 12 MPG to 18 MPG, best decision I ever could have done.

Unbelievable mileage increase

[This review was collected as part of a promotion.] wondering if these are counterfeit, after they all started breaking and looking horrible. I took them out and put the recommended stock ones in my Camaro. started reading online about counterfeit spark plugs, I've used the same brand in a Ford of mine and they were great, so I would be highly suspicious about these.
