Throttle Body Spacers cause the air molecules to organize and maintain high velocity. This helical effect provides a superior atomized mixture of fuel and air all the way into the combustion chamber. For drivers, this translates into more part-throttle torque, improved mid-range power, combustion efficiency and potential increases in fuel economy, depending on the driving conditions.
A high quality performance intake system is one of the best dollars to horsepower investments you can make. Performance air intake systems start with a more efficient air filter and then improve the air path between the filter and the motor, resulting in increased horsepower.
