# Airaid 520-538 - PowerAid Throttle Body Spacer Want to know a little secret about Airaid's PowerAid™ Throttle Body Spacer? The unique dyno-proven "Helix Bore" of the Poweraid throttle body spacers by Airaid causes a spinning action of the incoming air charge as it passes through the throttle body.
