In the quest for more air, the throttle body is the last assembly that can be modified before air enters the engine. Volant throttle body spacers employ a unique set of fins finely tuned to accelerate airflow and increase turbulence, producing higher air pressure. Increased air pressure enhances cylinder combustion, which increases throttle response and power. Volant throttle body spacers offer an affordable and efficient way to boost performance of your Truck, Jeep or SUV.
