Electrical energy from the engines ignition coil is stored in the built-in capacitor

At the exact moment needed, that energy is released in an amazingly powerful and quick (2 nanosecond) high-energy pulse

The improved combustion efficiency burns fuel sooner and more effectively, which equals improved mpg, less CO2 based emissions and better overall drivability

Tested Benefits:

Up to 12% more horsepower and torque

More precise and efficient combustion with fine-wire electrode

Better throttle response
