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.

Ease Of Installation

[This review was collected as part of a promotion.] Running smoother and faster. Definitely i great buy with these plugs. Will have to see what the dyno says too.

Noticeable difference

e3sparkplugs.com

[This review was collected as part of a promotion.] That's right. The only pre-gapped plugs. So far they are exceptional with a quicker start time as they seem to be able to fire on less fuel mixture in cylinder. Also same with outdoor power equipment plugs!

The only "pre-gapped" (officially) plugs.

[This review was collected as part of a promotion.] Start up is now immediate. Smoother idle and the "Go fast" pedal works much better. The benefit of these plugs outweighs the cost. Get them.

E3 48 Installation Acura 3.0L

[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.

[This review was collected as part of a promotion.] E3 spark plugs have been my go to. No issues, always working as intended/described. 

Impala, Sierra and now will be using them in my Tahoe, I have always found the performance to be where it should be.

 Without having to gap anything, its always a nice fit.

My Go To

[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!!

[This review was collected as part of a promotion.] Great plugs - work better than OEM. Great throttle response.

Upgrade your plugs to E3

[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

[This review was collected as part of a promotion.] The extra sized gap was exactly what I needed with a higher compression engine and a MSD ignition. Now it fires up immediately and my AFR is staying steadier than before.

The larger gap was exactly what I needed.

[This review was collected as part of a promotion.] Best spark plugs I have ever bought ! I have purchased these for everything I own that they currently make them for.

Perfect for performance of any machine

My car didn't want to start after installation I made sure obviously everything was plugged in and it was. bought brand new iridium plugs and it started right up

If you have an is300 don't buy
