very easy installation. 15 min. on F150 2006 stx 4.6L engine. I was hoping to get the whinning or whistling sound but I do hear a thoater noise when I step on the gas peddal.

I was very impressed with the look of the spacer, its a nice eye catcher under the hood. As far as performance goes i did notice a fair amount of low end power and torque. However the spacer does create a whistling noice have not decided if i like that or not yet? Overall i was very happy with the money to power ratio of this product. Oh and i saw a 1.7mpg in the city gain. not taken it on the highway drive yet.

Horrible whistle, just horrible. From the second you start the engine you get a terrible whistle. Very, very dissapointed in the product. I am sending it back for a full refund.

Installed the poweraid on my f150. felt a slight mid-range gain in power, and a few extra mpg. my only complaint is the whistle during acceleration. but you cant really hear it with the radio on. i would use the product again.

i installed this throttle spacer in about 15 min. very easy. i already have a k&n air intake installed, so with this added, there is a definate notice in a power gain. gas milage has improved about 3 mpg. the only downside to this product is the whistle it produces, other that, its great.

The throttle body spacer was quick and easy to install. I also installed a K&N Cold Air Intake system too. Together they have enhanced my low end torque and throttle response. Haven't had them long enough to gauge mpg improvement. The whistle from the throttle spacer can be a bit annoying, but a good stereo masks the sound.
