ImPoRtAnT CNG ISSUE

why is it necessary to block the air intake when installing a after market cng kit...i mean why cant we keep the engine at its original air intake and feed gas into it...like in my civic, the cng guy has installed a venturi over the air intake reducing the throat dia...why cant i just feed cng direct into the air filter box...without using venturi..what will be the reslts then?
