wow, i never thought a air filter could do that. So why havent this warning ever taken seriously? this is the 1st time i ever heard a negative thing about those super cheap airfilters.

 

i dont think its the seal not sealing right if its not sealed right it lets more air in through the gaps. mabey it causes turbulence. anyways if i run no filter at all the seal wouldnt be right would it...there would be no seal. i think its the foam filter. the filter probly made out of a sink sponge
