they are really only there to filter any dirt from getting to your engine and the engine will get more than enough air than it needs no matter what you use. People think that if they use a different filter they will get more air but as I say, it's getting more than it needs already and a filter won't 'force' more air into it.
Whilst I agree there are a lot of BS "power gain claims" out there, obviously due to the crowded marketplace, there is hard proof that different types of airfilter setups and specifications do affect the engine's performance.
The way I try to visualise it all, is this:
Standard OE panel airfilter: Imagine your sat inside a car, windows shut, trying to breathe with a thick sock over your mouth.
Aftermarket panel airfilter: Imagine your sat inside a car, windows shut, trying to breathe with a thin sock over your mouth.
Aftermarket open cone airfilter: Imagine your sat inside a car, windows open but the heaters are on now, trying to breathe... you'll inhale hot air when the car ain't moving, but much colder air when it's shifting along at speed.
Aftermarket sealed cone airfilter with airfeed (eg-viper): Imagine your sat inside a car, windows open but the heaters are still on, with your head out of the window all the time... you'll get cold air rammed down your throat at speed when you open your mouth (throttle). The heat inside the car will not affect you nearly as much because you're inhaling cold air.
Yes, an engine will only accept a certain volume of air, due to it's capacity, but with airfilters we're not trying to increase that, what we're doing is increasing airflow (breathability), ensuring that there is minimal restriction to getting this air into the engine, and also dealing with air temperatures.
