The PowerAid Throttle Body Spacers from AIRAID Premium Filter Company are designed to greatly improve the low-end torque and horsepower characteristics of your engine. PowerAid accomplishes this by spacing the throttle body one inch and adding a dyno-proven Helix style bore(s). As the intake air passes through the spacer, the Helix bore creates a vortex action that improves atomization creating a more complete combustion and an efficiently burning engine. The results are improved drivability and increased fuel efficiency. The PowerAid spacer is 50 state legal, will not void your new car warranty, and can be used with any grade fuel.

Does a throttle body spacer actually make a difference? 2004 6.0 f250
View Staff Answer 

The AIRAID THROTTLE BODY SPACER 400-601 is designed to increase low-end horsepower and torque by creating a vortex of air entering the engine. This “spiraling” air helps to increase atomization which in turn will increase drivability and fuel economy.
