So I just got a brand new 2009 Focus SE and I'm looking to do some hands on work with my new car. Recently I've been looking into different air intake kits and I just wanted some personal opinions on the different ones available and what you all prefer. I looked at a K&N cold air intake kit for about $325. If this is worth the cost then I have no problem paying that for it. By the way I'm only 20 and kind of a newbie to all of this but I'm always willing to learn. Thanks.
