Product Description

The Automobile Fuel Efficiency Improver reduces electrical interference in your vehicle's power system to cut your gas consumption by up to 20% - especially on older vehicles. Conditioning the vehicle's electrical systems allows its electronic control unit, fuel injection and engine timing equipment to operate more efficiently. When the engine runs more efficiently, it requires less fuel, produces more power and reduces CO2 emissions. It's simple and easy to use: just plug it into your cigarette lighter. Not for use on hybrid or electric cars.

Product Description

As a vehicle gets older, the power systems often will generate and experience more electrical noise or electrical interference. This electrical noise can have many detrimental effects on the vehicles systems and decrease their fuel efficiency. The FD-47 simply plugs into your lighter socket/power port and the power conditioning qualities of the FD-47 help to reduce and remove this noise and to restore your vehicles fuel efficiency. If your vehicle is designed for high performance or modified for increased power this unit may not have any effect on your fuel mileage. For maximum results use on vehicles that are over two years old.
