I have a new K&N panel filter (33-2270) for sale. This just drops in your stock intake airbox which replaces the typical paper filter allowing the car to breathe better. I would like to hand it over for $30. It is still in the plastic casing. Let me know.

Here is a link to see if this filter fits your Mini.
