I can tell you from personal experience, do not get one. For a carbuerated motor, they can work wonders, but do absolutely nothing for a fuel injected motor. They are a total waste of money on a fuel injected motor.

My buddy just put one on his Integra GSR and I've driven it before and after the install. My opinion is more throttle response but only if there is an after market intake installed. I've also driven a Civic with one installed and I noticed a bit more. For best results, install a 65mm throttle body and a cold air intake before getting a throttle body space. Sounds like a turbo without the blow off valve.
I think that the throry behind these TB spacers is that in effect, it will make the intake runners longer, therefore you will get more top end out of them. Also, some, if not all, have a swirl pattern built into them to gve the intake air a "swirling" motion creating faster intake speeds therefore better throttle response and a more complete burn. Thats my understanding of it anyway. I say if you can get one at a REALLY cheap price, try it, it's not gonna hurt anything, and you can always take it out. But make sure that if you try it, let us know of any differences you see or feel.

It spins your air so that It mixxes better with you fuel or something like that...My friend has one on this 03 civic Is sounds pretty cooland but the gain Isn't much maybe 1hp or so...
Includes all necessary gaskets and installation hardware. [/list]
POWERAID Throttle Body Spacers can be installed in less than 1 hour. In fact, most kits are ready to go in only half an hour, with no drilling or cutting required. A POWERAID Throttle Body Spacer is the ultimate intake system combination when teamed up with the AIRRAID Cold Air Intake System.

Word.
The idea is that a longer intake total length (from filter to valve) increases power by increasing air velocity. We already have long rnough total intake lengths.
The other main idea is that it works much better on metal intake manifolds and metal throttle bodies, by seperating them with an insulating material you reduce the intake charge temperature as well as slightly lengthening the intake, so you make the intake charge a little cooler and you gain a little performance.
But since SVTf's have plastic intakes, this would not benefit it much if at all.

This I will agree with. First, look at the intake manifold on the Focus. Im not sure about the Duratech's but the Zetecs have a 'U' shaped manifold, meaning the air comes in, through the throttle body DOWN the manifold then back up into the cylinders. A real strange way to do it in my opinion, but the SVT takes advantage of it with its dual runners.
Secondly with the Focus, as HTPerformance mentioned, having plastic intakes and manifolds, its not affected by heat in the way most are.
Now, having said that, I do have a spacer on the GTP. Why? 'Cause I have a metal intake (supercharger) in which a metal throttle body is mounted to. Furthermore, engine coolant is run through (or around depending on how you look at it) the throttle body.
After making a few 'test' runs I tried grabbing that throttle body. I would have sooner stuck my hand in acid than try and grab it again. So I got a spacer, not for any added air flow, but to isolate the throttle body from the supercharger and reduce the inlet temps. Perhaps not significantly, but every little bit helps when you're trying to reduce knock retard and reducing inlet temps does help that out. I will say this, after installing the spacer, I can grab the throttle body now.
There was a test done somewhere (I dont have the link anymore unfortunately) where they used thermal imaging to show the difference and use of the spacer reduced the temps, externally anyway, by some 40 - 50 degrees. Thats significant. While that may not translate to the same reduction in inlet temps, it does carry over to some degree and as mentioned, every little bit helps.
