(3-00151) K&N High Flow Air Filter (33-2070)
Direct replacement K&N drop in air filter. Get more performance, better fuel mileage out of a serviceable K&N high flow air filter.
BMW went to substantial effort to design the intake system and it works well. In fact it works better than a lot of the cheaper 'Cold Air Intakes' on the market. If you are looking for a performance enhancement for your intake and you're considering a second rate intake, save your money and just go with this K&N drop in filter.
