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.

I had to bore two holes out to make it fit the stock throttle body and manifold. There is no ‘whistle’ like the packaging says. There is no improved fuel economy. I’m disappointed with this purchase. Don’t waste your time, energy, or money.
