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.

Headquartered in Point Vedra, Florida, Pyrotek E3, d.b.a. E3 Spark Plugs, was formed to help customers increase power, improve fuel efficiency, and reduce engine emissions that contribute to global warming.

It is built to have a very cold heat range, non-resistor, and is used typically in top fuel drag racing engines and similar applications. It crosses against AR5383. E3 racing plugs are fitted with its patented DiamondFIRE ground electrode, which is secured with two legs to the shell.

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.

5 years How often you change the spark plugs in your vehicle depends upon the type of plugs you use and how you drive the vehicle. Naturally, better plugs and easy driving conditions are optimal. E3 automotive spark plugs offer a 100K mile warranty, or 5 years from the date of purchase.

When you race, every single component in your car matters, especially in the engine. The high performance racing demands from your engine means that not just any spark plugs will do. You need racing spark plugs with impeccable timing and just the right heat range.

Comparison of best spark plugs for 2022

Racing spark plugs for cars or motorcycles have been developed for fine-tuned engines designed to achieve maximum power under racing conditions. Unlike standard spark plugs, racing plugs prioritize performance and durability at peak speeds–often at the expense of efficiency at low-speeds.

Racing engines operate at high-power and deliver high-performance, which means they run hotter and vibrate more. Racing spark plugs perform the complicated task of delivering maximum engine power and dissipating heat under these challenging conditions.

The diamond spark is only something that can be observed in special conditions and is a visualization of light from a diamond that you normally cannot see. This makes it possible to visualize light coming from all directions.

By simply replacing your existing plugs with premium E3 spark plugs, your ride will have the performance it deserves. Horsepower gains of 4-6% can be expected, depending on engine class size.

However, iridium makes the best spark plugs for several reasons. A major downside to copper spark plugs is that they have to be replaced soon because the heat inside your engine and the sparks produced make the copper start deteriorate with time. It will bring down the performance of your engine considerably.

In racing, timing is everything– when you cut a turn, how quickly your throttle responds on the straightaways– and nowhere is this more important than in your racing engine. Pulstar spark plugs deliver the most rapid, powerful, consistent combustion of any product on the market.

While spark plugs don't technically increase your engine's horsepower, they bring it back to its optimal combustion level. In simple words, your car will run as if it's new with optimum acceleration control and improved fuel economy! Keeping that in mind, let's look at some other related queries about spark plugs.

Platinum plugs deliver enhanced performance and fuel efficiency compared to copper plugs, but for a considerably cheaper price than iridium spark plugs. Much like iridium plugs, platinum spark plugs operate at a lower temperature than copper spark plugs. They can also last up to twice as long as basic copper plugs.
