Quạt turbo tăng áp giúp tiết kiệm không khí

This Double Propellers Fuel Saver Turbonator Fan provides a more dynamic control over the intake system by forcing powerful airflow into the combustion chamber at a high speed. Once the engine is started, the propellers spin to create a maximum turbulence in the incoming airstream to allow enhanced fuel atomization in the combustion chamber, resulting in significant increase in horsepower and better gas / fuel millage. With simple installation steps, you can enjoy going faster and furtherer whilst saving gasoline all at the same time!
