Description
The AIRAID Throttle Body Spacer is engineered to increase off-idle torque from roughly 800 rpm up to 3,000 rpm. Its patented Helix Bore design creates a spinning airflow as it moves through the spacer, boosting air velocity and improving atomization of the air/fuel mixture before it enters the combustion chamber. The result is enhanced part-throttle torque and stronger mid-range power.
