Wow- now that guy knows what he is talking about. Still, my old Aztek filtered much better than the Civic, so I guess the question is, can the we get a Micron air filter (which I assume has the charcol embedded as well) instead of the standard paper filter. Maybe I will suplement the normal filter as I have read with a charcol pad (but heading the advice of the above poster- I don't want to over work the air pump).

Thanks
