Here is part two of the video series that describes how to make a electronic fuel injector enhancer (EFIE) device that will maximize fuel economy from using an HHO generator.

Where to Purchase if you don’t want to make one:

There are kits/instructions available from sites that will tell you how to make your own EFIE, but if you don’t have time or the skill to make one there are stores that sell already build EFIEs. If you have purchased an HHO kit or are considering it for a fuel injected vehicle, go to EFIE Devices, to get an already assembled EFIE device.
