Tjis filters out dirt while taking in air ti mix with gas to combust. The whole should have a sensor plugged in it to allow for computer to pick up more free flow air and adjust mixture so your air intake is not just show.

Dont disconnect this tube as this is for the Positive crankcase ventilation system (PCV). This helps recirculate the bly-by that the pistons wrings couldnt help seal out. Also this helps with the emissions on the car. It doesnt affect the emissions much but if you live in California youll need all the help you can get especially if your car has high miles. This is just my two cents.

Adding just a filter is rather a bad idea for a NA motor. You would now induce humid air into the motor as the PCV system is supposed to be sealed. The location that this filter is located at, is supposed to see a draw from the intake, applying a small vaccum to the valve cover. Thusly the addition of this filter is having the same affect as creating a vaccum leak(down thru the oil drains in the head, thru the block,the PCV valve and directly to the IM).
