AIRAID Throttle Body Spacer Ford - 400-619

AIRAID Throttle Body Spacer - Model AIR-400-619

The AIRAID Throttle Body Spacer is engineered to boost your vehicle's off-idle torque, specifically between 800 rpm and 3,000 rpm. Thanks to its innovative Helix Bore design, this spacer enhances the airflow by spinning the incoming air charge as it moves through the throttle body. This spinning action increases the velocity of the air, leading to better atomization of the air/fuel mixture as it enters the combustion chamber. The result? More part-throttle torque and improved mid-range power that you can feel every time you hit the gas.
