x 60mm length: 76mm, weight about 236 grams. Built-in two independent motors with different speeds (a total of 4 high-speed ball bearings), two fans, double-sided blade reversal unique design to ensure sufficient wind pressure. The air inlet fan is 7 blades, and the air outlet fan blade is 5 blades. When the turbine is working, the wind enters the wind from the 1 wind turbine of 16, 000 rpm, and then the wind pressure is reversed by 12, 000 rpm. Let the boost effect be maximized!! Save fuel by 5%-20%. (depending on specific conditions) Reduce harmful emissions. Reduce the carbon deposit inside the internal combustion engine and prolong the service life of the engine. Increase engine power by 10% to 20%, vehicle is starting, power is enhanced when using air conditioning or rapid acceleration
