Air foil on a 96 vette
Do these actually do anything or are they a waste of $. Though I am not expecting anthing like 14 horse power, could I expect anything? Is it worth $40?

Gordon Killebrew mentioned that on many occasions when he pulled someone's intake duct off, the airfoil was not even in place, it was more of a restriction than anything.For a stock LT1 you can skip it.

Thanks guys,
I have enough paper weights as it is.
I though it might be to good to be true. Any ideas on how get a little more juice for around $200 or $300. My car is completely stock and I am spending most of my money on cosmetic repair or replacment right now. Just had a couple hundred bucks I wanted to put toward performance. Not much performance, but a little.

I found it pretty interesting, though, how a few weeks ago somebody chimed in with *favorable* things to say about the airfoil - not dyno proven numbers - but a better feel. Wouldn't ya' know it, people came out of the WOODWORK who also had airfoils in their cars...and not just noobs - veteran members here. Racers, even. I don't have an airfoil, so don't get the wrong idea, but don't you find it slightly interesting that high-hp application cars (i.e., C5R, etc.) have airfoils? Additionally, don't many aftermarket TBs essentially "come" with an airfoil? Not some part you install, but rather it's incorporated into the TB itself?
Hmmm.... Yeah, they maybe not worth the $50 on an otherwise stock vehicle, but if your car has one, it can't hurt. Just my 2c.

I believe somehere said it was good between 5000-5500 rpm.
You have to ask why GM didn't use it in the first place.
Yes the aftermarket TB's have them built in, but does it do anything?
Like I stated above, if it falls out and you don't know it, it's a hinderance.
If it's built in or cast in or screwed on, it won't fall off, and I'm sure it wouldn't hurt, but will there be a significant gain? You can't feel 5 hp.
The LT1 air foil just presses into place, therefore it's easier to fall out.

Honestly
I descreened the MAFS, installed an open air lid, and K&N filter, did the TB bypass and installed a Throttle Body chip, and an Air Foil.
I felt a very signifigant SOTP increase. Mine bolts in, and hasnt come loose or nothing. I did notice the car ran slightly smoother, and revved faster.
Id say its worth it.

I was looking around this morning for something else and ran across this on Midamerica works. 
They have it for sale for 29 dollars. Is this the kind that bolts in?

One thing I noticed for these screw in setups is that you need to locktite the bolt or it will back out... I never had one fall off and block airflow, but I did find it loose once...
Right now the airfoil is sitting on a shelf in my garage... I'll probably install it only because I have it but I wouldn't go out and buy another one knowing what I know now...
I don't know that it did anything for me, but I really don't see how a properly installed one would hurt...

From: Lahaina Hi
I have one but I ported my throttle body to match and the air flow has to be better but I don't think you would see any results at anything below 80 mph.
I did see some improvment at around 110 mph after I removed my maf screen the foil seemed to calm the voltage power spikes I was getting after removing maf screen.
But I use TTS and tuner cats to keep a check on my engine.
Yes that is the metal one in the picture.
I would spend my money on a power programer!!
