The FD-47 increases a vehicle's mile per gallon (MPG) through power conditioning of the vehicle's electrical systems. Conditioned and clean power allows the vehicle's electronic control unit (ECU), fuel injection and engine timing equipment to operate more efficiently. When the vehicle's engine runs more efficiently it will require less fuel, produce more power and have reduced exhaust emissions (reduced CO2).
  • Power conditioner that can increase fuel economy and reduce emissions

The FD-47 simply plugs into the lighter socket/power port and the power conditioning qualities of the FD-47 help to reduce and remove this noise and to restore your vehicle's efficiency.
