        			Principle: The main fuel pressure is to increase the nozzle pressure, so that the fuel spray into the mist, the fuel mixture ratio to enhance combustion more fully, so as to enhance power, is the real fuel and power is proportional! The main function of the installation of the fuel booster is to improve the EFI engine fuel pressure, and fuel pressure increases, the nozzle fuel spray atomization finer, more complete combustion. And then do not change the fuel supply mode to increase the amount of fuel injection (about 5% -10% increase). To enhance the power, increase the role of torque. Is also the least expensive and the role of a modified product. If the car at the start, uphill, you feel it powerless, lack of motivation, then the car&apos;s torque is insufficient. At this time, I suggest you install a fuel booster. The working principle and the original car fuel pipeline pressure control valve is basically the same, but the modified car used supercharger is a pressure control valve can be adjusted, generally speaking from experience, the control valve after installation, according to experience and science Using the principle, the fuel pressure of the engine can be adjusted to 2KG-3.7KG under the control of this device. Specifications: Color: silver, blue, yellow, purple Product size: 90 x 65 x 48mm/3.54 x 2.56 x 1.89&quot; Gross weight: 265g  Notes:   It is not applicable to cars with no oil return pipe.  Fuel booster is installed on the oil return pipe which is behind the pressure regulator. The fuel injection pressure of the fuel injector can be increased by adjusting it. The fuel injection pressure of the fuel injector can be increased to about 3.0-5.5 kg (usually, the pressure is 3.0 kg or so, generally adjustable to 3.7kg), which is comfortable pressure on the nozzle.Package included:1 x Car Fuel Pressure Regulator 1 x Oil Pressure Gauge 2 x Plugs

## Features
