I am thinking about putting this on my F150. Of coarse this is after the fact that I have the Airaid Air intake system on my truck already. If I do this what will it do to my tunes. Will have I have upgrade them to allow for the change. Can you help me out Mike.

 

i dont think you should put a throttlebody spacer, im pretty sure they dont do any good...

 

They make a great paperweight.

 

I will try to find the consumer report articals I have read and add a link.. The thing is apperently useless. There are no actual dyno proven benefits. I was gonna get one until i read all the "mythbusters" type reports dissing it.

 

All I could find is thousands of articals that say how awesome throttle body spacers are. They all seem to mention how much controversy surrounds them too.. They seem to be aimed at older carborated engines. If anything the anodized red spacer looks nice and can't hurt.. haha

 

It's a $90 paper weight...don't do it!!!!!

 

Ditto. Didn't do squat for my 2000 5.4 except make an obnoxious whistle sound. I have yet to hear anyone say it had any positive impact on their fuel injected motor. However, on a carborated motor there is some documented benefit although not much.

Bottom line - don't waste your $$$

 

You can do a search to look up some of our older posts on this to get some info....

If you do, you will see that we talk about how on some vehicles that use the older TBI type of fuel injection (like older GM trucks and even some Mopars up thru about 2003), a throttle body spacer can in fact add power, it does it by adding plenum volume - this is an old drag racer's trick to get a bit more power on the top end, mostly.

However, for these F-150's, we don't recommend spending the money for a throttle body spacer, it just doesn't do anything for these particular trucks due to their design.
