🔥 Enhance Performance with Airaid 300-577 PowerAid Throttle Body Spacer Review

Definitely more power at low and mid frequencies. That whistling noise people complain about? I can't hear it, but maybe it's the Magnaflow exhaust and Mud 35s on my 2005 Hemi Power Wagon. Well worth the money and 30 minutes to set up if you want a little more power. Highly recommended!

Love the addition to the factory throttle body, definitely a plus for the car. 08 Chrysler Aspen 5.7 Hemi v8. Love the whistling sound it makes and you accelerate and shift. People come to my car and ask what I'm pushing. Everything is stock except k&n intKe spacers and flow pens, everything else is Hemi Baby.

I bought this for my 2003 Dodge Ram 1500 5.7 and also installed a K&N air intake and definitely feel more throttle response. Also a slight whistle. not annoying as others claim. Love it and hope to see better mpg than it claims with an air intake. The equipment that comes with it is also perfect.

Pretty loud! Really sounds like belt slippage as another reviewer said. It doesn't shape or shape a sound in any way, even close to a turbo like others have said. You've probably never heard one. I've had it on my trailer for a few weeks now. It will come out at the next opportunity. Although the installation was very easy. Directions were good. Didn't notice any difference in performance/response.
