Product Description
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.

Instant power increase!
By Red Robin
This is the single cheapest part to add 10 to 20 more HP right off the line and thru the midrange cycle. Other reviewers not that impressed, but using this spacer with the k&n air filter makes my 2010 5.4 L sound as good as it runs. No truck touches me anymore and I get out of first gear so fast now I have to wait for second or the truck will break loose like crazy! So pleased, way to go PowerAid!!!

Performance not noticed
By Mike
I've had this on my truck for about 2 months now. I haven't noticed any difference in performance or gas mileage. I am still testing the truck to see if there is an actual improvement in fuel economy. I installed this with a K&N filter. I installed this on a 2005 Ford F150 FX4.

By Chris Ellis
Installed w/ SynthaMax filter kit. Fit perfectly under the hood.Looks great. Easy to install. The back of the throttle body is alittle tough to get to...small hands would be better.The "whistle" can't be heard if the radio's on (with very little volume). "Normal" ears won't notice it.It does sound like a factory turbo spooling up. The theory is questionable but, the overall unit & installation is pretty cool.I assume it allows for better operation...
