Product details
The POWERAID Throttle Body Spacer is designed to enhance off-idle torque from 800 rpm to approximately 3,000 rpm. The spacer utilizes it's unique, patented Helix Bore design to spin the incoming air charge as it passes through the throttle body spacer. The spinning air action boosts the velocity of the incoming air and contributes to better atomization of the air/fuel mixture as the air charge enters the combustion chamber. The end result is more part-throttle torque and improved mid-range power. 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. The POWERAID Throttle Body Spacer is designed to enhance mid-range torque using a patented Helix Bore which spins intake air going through the throttle body spacer.
