Any Interest For A New !!BETTER!!! Air LiD?
that being said, . im interested also, . if it can be backed up with proof

a) What it looks like
b) How it performs
c) How much it costs
If it's expensive, ugly as sin and performs like **** then no wonder no ones bothered, but without pics and more info it's hard to tell at this point in time.
The only known and accepted method of forcing air is by compression. As the molecules are sparse a gases form such as air can easily be compressed to result in a higher volume of gas for the displacement.
Turbo and supercharges are accepted forms of of compression.
There are other methods such as the use of air dams and well designed intake systems. However to acheive significant compression, i.e. Ram Air you really need to be traverlling at about 350mph, it takes about 200mph before you even notice the gains.
FYI - at sub-sonic speeds to increase air pressure is done by slowing the velocity of the air, this is achieved via an opening of the passage or a reverse funnel. Hence why many race cars have very large air boxes with smallish openings on them.
If you have a regular funnel shape narrowing down then at sub-sonic speeds you are actually having an adverse affect.
At supersonic speeds (very rare for cars) the opporsit is true however.
Airbox resonance is another neat trick ofen emplyed in airbox design and again is part of the reason why competition cars have large air boxes. You can also tune the intake runners to match the engines natural harmonic frequency to promote smoother air flow.
