The result of independent research and testing suggests that using E3 car spark plugs in your vehicle can increase horsepower when compared to more conventional spark plugs. Our patented Edge-to-Edge ground electrode outperformed other plug designs, including premium spark plugs offered by the major manufacturers. Plus the good news is E3 automotive spark plugs will continue to offer that "like-new" performance over the long haul and help to extend the life of your car's engine. This means less money out of your pocket.

Regardless of the brand, model or style of the vehicle that you drive, our plugs are designed to deliver an optimum spark to your car's new or aging engine. Developed in conjunction with researchers from leading universities, we designed our car spark plug to create a faster flame front, so the unburned air-fuel mixtures that would normally pass into the engine's exhaust system experience a more complete burn. Isn't it about time to put the DiamondFIRE power of our car spark plugs to work in your car, SUV, minivan, truck, motorcycle, snowmobile or ATV?

E3 automotive spark plugs utilize the latest E3 technologies to help engines operate more efficiently by burning fuel more completely. Our patented DiamondFIRE ground electrode gets the flame (or combustion process) started earlier in the combustion chamber before gas is vented off when the exhaust valves open. Although results may vary dramatically based upon piston displacement and operating conditions, increased combustion efficiency and a faster burn allow E3 equipped engines to minimize the venting of unburned (wasted) fuel.

E3 has taken the lead in developing a superior car spark plug design that offers several benefits to our customers. Most spark plugs create a flame shape that moves sideways, outward from the electrode. Thanks to E3's diamond-shaped architecture, the flame kernel moves toward the air/fuel mixture to create higher combustion pressure. This in turn allows for a better burn and the combusted mixture exhausts more easily for improved fuel efficiency.
