The Airaid PowerAid Throttle Body Spacer is developed to enhance off-idle torque, from 800 RPM to approximately 3,000 RPM. It incorporates a patented helix bore, which causes a spinning action of the incoming air-charge as it passes through the throttle body spacer. This improved air-charge carries all the way into the combustion chamber, producing a super-atomized mixture, which produces tremendous gains in mid-range power and overall combustion efficiency for better fuel economy.

The product specs are incorrect; this is a perfect fit for the bade model 2004 Ford Mustang V6.I can't detect any significant performance improvement yet, but every little bit helps.
