Pulstar – Spark Plug with PlasmaCore (Part No.EF1H10)

Spark Plug with PlasmaCore

from

$14.99
Pulstar Spark Plugs use innovative plasma-assisted combustion technology to increase horsepower and torque. Plasma-assisted combustion is already used to improve engine performance in race cars, but requires complex control systems and costs nearly $2,000 per cylinder. Pulstar Spark Plugs, manufactured by Enerpulse Technologies, brings plasma-assisted combustion to consumers with a simple spark plug upgrade. Pulstar uses a patented internal capacitor, developed with the help of a US DoE laboratory, to create a high-intensity electrical pulse that ionizes the air-fuel mixture and saturates it with combustion-enhancing plasma. With its plasma-assisted combustion, Pulstar ignites fuel instantly and burns it rapidly; gaining up to 7 horsepower, 9 ft.-lbs. of torque … and, delivering wicked throttle response.
