Fuel Doctor's FD-47 is the Fuel Efficiency Booster! The FD-47 increases a vehicle’s miles 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 vehicles engine runs more efficiently it will require less fuel, produce more power and have reduced exhaust emissions (reduced CO2). As a vehicle matures, the power systems tend to generate and experience more electrical noise or electrical interference.  This noise can have many detrimental effects on the vehicle’s systems and decrease their efficiency.  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.

Don’t sacrifice your outlet! Fuel Doctor’s FD-38 Power Port Splitter for multiple charging is a quick and easy way to add an additional Power Port socket to any vehicle. Just plug it in to your lighter socket and make sure you plug the FD-47 in the socket with the silver ring. There is also an LED light that lets you know the adapter is active and has a built-in fuse for protection. Ideal for portable cassette players, boom boxes, radar detectors, cell phone chargers, or any other 12 volt accessory that you use in your car.

The FD-47 CAN NOT be used on Hybrids or Electrical Vehicles and works best on cars 24 months or older. Please note that the optional FD-38 Power Port Splitter is not required for the FD-47 to operate.
