Anyone tried a dual intake to the Air meter?

I was thinking that maybe adding a y pipe before the air meter, run 2 cones out front getting cold air and ram air when moving..

I assume this would increase the amount of air available to the air meter.

Would it be crazy to say with double the amount of air coming into the air meter, would this increase power?

The air meter will not measure pressure, but will it measure it to the point that it feels resistance from the flapper door being pushed back by the spring??

hmm wow well it seems kinda pointless to me because the amount of air comming in is already not restricted at all by simply adding a cone filter, i think the only way for it to be twice as much air would be to have 2 afm's cuz that way the engine actually knows its pullng in twice as much air.
ahh anyways cool idea i just dont think youd see a change
my .02 cents anyway...

I was kinda thinking since my car is so rich all the time.. If I added more air than metered for, it may make it slightly leaner and thus make more power.. Just an stupid idea.

It just seems to me that if I could push 6 square inchs of air as opposed to 3" stock, it would make more power from the added oxygen. I wanted to say it would double it, but I think it all depends how fast you are going and if the ram air is actually ramming air into the intake tract...

I think if these factors were all present it would make a small gain for little to no money..but any gains is good with me...

I think I may try this unless anyone has any reasons this would be a bad idea?

Considering that the rest of the intake system downwind is ported etc. the most restrictive part of the system becomes the MAF sensor or air meter if you will. Although two filters will decrease resistance to air flow the restriction and turbulence caused by the MAF sensor will stop you from seeing a noticable difference. The colder and consequently denser air will definitely be a plus, but I would imagine it would be no more than a single filter system drawing from the same place.
The MAF sensor is designed to measure the mass of the air moving into the engine. The mass of the air is affected by temperature and pressure, so, ignoring any shortcomings the sensor may have, it should measure accurately whether the air is pressurized or not.

I may be wrong here though, when I was in college working on the SAE race car one of the students said when he put some 1/2" square wire mesh on the flow bench flow dropped by 10%.
