Ok so I went to the store (Autozone) and ordered a K&N air filter... I pick it up and its a flat filter... I told them it should be a cone filter not flat... the one i have in there now is round so wtf... I told the guy this and he tells me oh you must have gone from a flat filter to a round one, best thing I can tell you is to come in and get your money back... Ok... Why is this such a big problem?
