ABOUT Pyrotek E3®

The spark plug is a critical device that supplies the spark (or flame kernel) for your car, truck, motorcycle or small engine. However, the basic plug design really hasn’t changed that much since the original ones used by Henry Ford back in 1904. Our company was formed to find a better design that would provide E3 customers with performance advantages such as increased power, improved fuel efficiency and a reduction in hazardous engine emissions that can contribute to global warming.
Today, E3 remains dedicated to reducing greenhouse gas emissions by limiting the amount of unburned fuel.
