Airaid, 400-521

Airaid Throttle Body Spacer 400-521


Bolt On Horsepower!
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.
