The E3 Spark Plug is proven to vastly enhance your Chevy Silverado and give dramatic results—increased horsepower, extended engine life, and improved fuel economy. E3 has a patented DiamondFire technology proven to be the most powerful way to ignite the air/fuel mixture for the most efficient combustion and longest performance life. Until now, spark plug technology hasn't changed much from the original 1903 patent for the flat "J-Wire" electrode that you see on most plugs. E3 has vastly improved that design and expanded on the capabilities in a way previously unthought of. 

E3 Spark Plugs increase engine power up to 12%. Thanks in part to the DiamondFire design, E3 Spark Plugs provide your engine with a more thorough, complete combustion, which results in better fuel economy and reduces fuel consumption up to 13%. This is an investment that will pay for itself a million times over for years to come.

Because of the cleaner, more thorough combustion, harmful toxic emissions resulting from unused and unburned fuel are reduced by as much 58%. E3 Spark Plugs reduce carbon deposits and material degradation inside your engine, extending engine life and promoting like-new performance. All E3 Spark Plugs are warranted against fouling, wear, and defects in materials and workmanship for 5 years or 100,000 miles.

Silverado Plugs

The engine has smoothed out like it ran when new. The power is back as well as the instant response. I really think the plugs make a big difference. I look forward to putting them under the heavy load of pulling to see how they perform. If the current performance is any indication I will not be disappointed.

I noticed immediate results once this quality coil was installed. Both in accelleration and MPG. Installed the E3 plugs and Magnecor wire set as well. Impressed with the quality and ease of installation. Highly recommend!

E3 spark plugs

Have put this car through multiple tests to see if the performance had changed any. Well i must say it got some spunk to it now that it never had before. Gave it the challenge of going up a mountain to see how much speed it would lose on the pull up and I'm proud to say it only lost maybe 2 mph on the uphill climb. Have put it onto a difficult interstate road where rapid pickup is essential on entering the roadway and the acceleration level was fantastic. Have already started to see fuel mileage improvement even with the computer readjusting itself to the new style of spark plugs. I would highly recommend anybody who wants their vehicle to run top notch to put these plugs in.

E3 plug power

The plugs do everything that they promised. The car seems to run smoother, accelerate faster, and my fuel seems to last a little longer. The car now idles at a much lower rpm and when giving it hell the engine seems to put out the speed without working so hard or acting like its being pushed to hard. overall id say these plugs were worth the money.

Extended Power!

The e3 plugs are an essential in all my vehicles. Not only are they an economic plus but also the added horsepower is great when entering the interstate. I save gas add power and emit less emissions. Nothing better for the money. Pay for themselves the first month.

E3 Spark Plugs

At first I did not know if they would work. I had to learn how to but them in since I had electronic ignition. After removing the head of the ignition and the 7 inch tube that was attached I used a long extension with a racket and removed them. It seemed like a great amount of money for spark plugs but it was well worth it after I put them in. With the big engine I have now it purrrrs like a kitten. Before my truck was kind of missing and not sounding to good especially after never replacing them since I bought the truck. Also I now have great acceleration when I take off. I would highly recommend this product to anyone. I love this product. Ray D 2005 Nissan Titan LE 5.6L V8
