What is the main benefit of the Helix Bore design?

The Helix Bore design spins the incoming air charge. This increases air velocity and helps the air and fuel mix together better before it enters the engine, leading to improved torque and mid-range power.

Does this throttle body spacer come with new gaskets or hardware?

The manufacturer description does not specify if new gaskets or hardware are included. It is recommended to check the 'What's Included' section or contact the manufacturer for details.

Will this spacer affect my truck's fuel economy?

While the primary goal is improved torque and mid-range power, better air/fuel atomization can sometimes lead to more efficient combustion. However, significant fuel economy gains are not guaranteed and depend heavily on driving habits.

About this part

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 designed to enhance off-idle torque from 800 rpm to approximately 3,000 rpm.
