This is example is to give you a good idea although it is not exactly the same because one side of the filter is not completely blocked off to air as the cup. But if you poked a small hole in the back of the cup then the cup that was slid in would come out easier. If you make a big hole on back of the cup it will come right out. Because the air did not resist. It flowed straight thrue the cup that had a cup in it. Same concept. Resistance abosrbs energy.

Not only does it create less resistance but it makes for a more combustible enviroment enabling the engine to compact more air into the cylinder at any given time.

It is only logical that a better flowing filter make better MPG.But that does not mean it flows signifigantly better on every vehicle it is apllied to so I am not saying all vehicles will see an increase but I have never had a vehicle not increase in MPG or power with a K&n filter. I cant speak for anyone else.
