The Vehicle Fuel Efficiency Booster.

This is the device that improves a vehicle's fuel efficiency by up to 18%. An independent automotive testing service showed the unit increased a test vehicle's average fuel efficiency from 23.8 to 28.1 miles per gallon in two weeks. The device simply plugs into a vehicle's DC outlet and stabilizes the electrical current flowing to the electrical control unit (ECU) - the computer that controls the engine's fuel injection and ignition systems - to optimize engine efficiency and improve gas mileage. It also mitigates electrical interference from the stereo, lights, or air conditioning that can negatively affect the ECU's ability to optimize fuel injection and fuel efficiency. Includes an adapter with two DC outlets that accommodate the fuel efficiency booster and another device. For use with vehicles that are at least two years old and have 12-volt systems; not for use with hybrid vehicles. 4" L x 1 1/2" W x 1" D. (4 oz.)
