I just installed an air flow system in my volvo s80 and im wondering first, if i have a breather filter, do i need any hoses running to it besides the mass air flow??(no right? because the hose that comes off the engine that sucks in air is being used by the breather filter?) and i have a sliver 21/2. 3 inch tube made out of like tin foil with wire going around the tube that was running to the bottom back part of my factory box, it blows out warm air, what should i do should i cut the piece of my factory air filter box that goes to that tube out and hook it back up or just let the hose blow out the air, and just so you know the piece that i would be cutting off my filter box has a special valve in it, i know its important on the factory hook up but i probably dont need it right?? just wondering
