Greatly improved the torque in the mid-bottom speed of the car and increased the intake air flow.It is convenient for the gasoline in the cabin to burn more fully,and the throttle feels lighter and more flexible.It can also play the role of fuel saving,fuel saving rate is 5%-15% or more,regardless of model Installed on the intake hose of the engine,when the engine is normally started,the inertial pulling force of the natural intake of the engine is used to drive the space wheel to rotate at a high speed,and a large amount of fresh air is continuously driven into the engine while rotating.At the same time,the incoming air is vortexed in a forced manner,so that the high-speed rotating air can be mixed with the fuel injected from the injector,and the air density in the intake hose can be greatly improved,and the mixture efficiency can be greatly improved.Increase,the explosive power will be produced when burning,and actually improve the powerColor:BlueMaterial:aluminum alloySize:6.4*4.9cmInstallation method:1.Remove the air intake hose and loosen the clip2.Pull the double propeller into the intake hose3.Install the intake hose and tightenPackage Contents:1* intake fan2* rubber bracketOnly the above package content, other products are not included.Note: Light shooting and different displays may cause the color of the item in the picture a little different from the real thing.
