Dual Oxygen Sensor Enhancers only $34.99 Shipped!!

These enhancers include about 1 foot of wire soldered to the board which is plenty for you to splice off of. They can be used as a single unit as well if you are only trying to control one oxygen sensor. It that case, simply follow the instructions on only using one output.

These are a must have if you are using an HHO generator because the gas mileage benefits are not seen with out an EFIE to control the gasoline or diesel. This enhancer is precision soldered using only the best components. This particular enhancer has two 20 turn potentiometers so you can fine tune the output very precisely. Not like those other guys were you only get half a centimeter to dial in your car. I am a professional and this product will last you a life time. It is based off of the zero fossil fuels (alt-nrg) design and components. These are not in an enclosure yet, and will need to be protected, so I suggest getting a small enclosure from radio shack to contain them. I am working on finding a good enclosure that I can mount them in. All enhancers are tested prior to leaving our facility and directions are sent promptly after payment has been received.
