okay, first of all, why the hell would you want to run a cai without a filter? you are just asking for a bird to fly up in there. 2nd, too much air? that might just be the stupidest thing i heard all week. unless you are talking about FORCED induction, you can never have too much air, but to get that air without using a filter, thats like boning a hooker without a condom...something is bound to get fucked up.
