E3 Spark Plugs

Born to Burn

The basic spark plug construction hadn't changed that much since the original plugs were used by Henry Ford in 1904. Most drivers would probably argue that changes are needed. They just didn't hear about E3. Based in Ponte Verda, Florida, E3 is a home to the advanced DiamondFire Technology spark plugs. The newly developed design of the components is made for improved horsepower, increased fuel efficiency, and reduction in engine emissions.

But how did the manufacturer achieve such outstanding results? With decades of successful experience in spark plug engineering and development, the principals of E3 arrived at a decision that the key to producing a better quality spark plug did not lie in the use of superior grade materials, such as platinum or iridium. Instead, they discovered an efficient new approach to the design of the spark plug's electrode to allow for improved ignition of raw fuel inside the engine's combustion chamber.

The new advanced design of the plug was met with a huge ovation. All those amenities were the result of improvement in directing the spark and faster flame speed, that in its turn was ensured thanks to the sophisticated DiamondFire Technology. In the process of evolution, their spark plugs burned fuel, improved power response, and cut toxic emissions more and more efficiently. In the world of today, E3 remains dedicated to providing their numerous fans with a better burn for their small engine, power sports, and automotive spark plugs.


If you're still iffy about placing an order for these highly-efficient spark plugs by E3 and want to go for further investigation, wait until you know about what the company can provide you with. Every automotive spark plug is warranted to give you experience of more power on less gas, quicker starts and less fouling than competitive spark plugs. In addition, the item is guaranteed to be free from defects in material or workmanship for a period of 5 years or 100,000 miles from the date of purchase. What will you say now? Decided to stop your searching journey and stay with E3? Indeed, a smart person makes smart decisions.

E3 Spark Plugs
1998 Honda Civic Si
| Posted by | (Saskatoon, SK)

These spark plugs do what E3 says they will do. I have already noticed the fuel economy boost and the horsepower gain from these spark plugs. I also have not experienced any problems with my 98 Honda Civic Si, and it's been in there for about a month now. It is definitely worth buying!

E3 Plugs
2006 Kia Spectra
| Posted by | (Laval, QC)

Got these installed in my Kia Spectra '06 just fine. Car started up right away and is running good a week later. Didn't really give me a performance boost but I drive like a grandma anyways to preserve my car in every sense. If these last a good 60,000 miles I'll be really happy with this.

1993 Honda Del Sol
| Posted by | (Selma, TX)

I own a '93 Honda Del Sol 1.5 Si base engine with fuel injection. Trips taken in this vehicle can be long 350+ miles and return the same day. Until recently, unrefueled range on the car was 280 miles; since putting in 4 E3 spark plugs range is 340 miles at 70-75 mph. I have tried Bosch +4, Split Fire, and NGK platinum. This plug's performance in my vehicle is superior; it yields greater gas mileage, torque, and speed.

The plugs were a direct match for my vehicle - CARiD matched the part perfectly. I'm not sure if I notice any gains in horsepower or MPG, but it was time to change my spark plugs. Satisfied customer.

2008 Hyundai Tiburon
| Posted by | (Yonkers, NY)

Just installed a set of E3 plugs in my '08 Hyundai Tiburon SE V6. Fried out the original plugs in 21K miles and was running a bit rough. The new E3 plugs netted 30.1 mpg on the first tank after the change and 30.4 mpg on the second fill up. The original plugs were still getting around 26-27 so I like the new plugs. The car starts better and runs more smoothly, so I would say these are winners. I also put a set in my '06 Sonata V6 and have noted about a 2 mpg increase there too.

2001 Nissan Altima

I drive a 2001 Nissan Altima. I put these plugs in after seeing them tested on TV. I got an instant increase in power, and as long as I keep my foot out of it, I also get better mileage.
