Competitive Spark Plugs
Problem with "J-Wire" Electrode Design
Some competitive spark plugs feature problematic designs like the traditional J-wire where the ground electrode can actually get in the way of the flame kernel as it travels away from the plug's gap. This can sometimes interfere with the combustion of the compressed air-fuel mixture. To ensure a more complete combustion, we recognized that the flame front must reach the compressed gases as quickly as possible. That is why the E3 DiamondFire design is open at the end. Our flame kernel can travel directly toward the remaining air-fuel mix.
"Fine Wire" Precious Metal Electrodes
Manufacturers of spark plugs that use precious metals in their electrode were quick to look for ways to reduce production costs. Thus, the "fine wire" electrode was introduced to reduce the amount of metal used to produce their premium plugs. The challenge was the fine wire design wouldn't have a very long useful life, so platinum or iridium was added to help extend the useful life of the plug. Because of their basic design modifications, fine-wire spark plugs have fewer misfires. But, the E3 DiamondFire design with its multiple exposed edges still out performs fine-wire plugs by maximizing the spark presentation in the combustion chamber.
A Faster Electrical-to-Chemical Transfer
We feel our most significant research discovery came from understanding that having two sharp edges firing to each other is an improvement over an edge-to-flat electrode design. Sharp edge-to-edge designs force the electrons to form a stronger plasma channel faster. That lets our DiamondFire spark plugs reduce ignition delay and offers a measurable improvement in the electrical-to-chemical energy transfer. If you're looking for a faster flame, a more complete combustion, an improved engine response and higher fuel efficiency, remember E3 spark plugs are "Born to Burn".
