AIR FILTER K&N BM-1010 BMW S 1000 RR 2009-2011

K&N filters (made in the USA) ensure the best filtering efficiency and maximum air flow.

They replace the original filter, ensuring an increase in torque and power, as well as longer engine life.

Indispensable in combination with "open" exhaust systems and/or with additional injection control units.

Unlike normal paper filters, K&N filters do not require replacement at the expected mileage, since it is possible to restore the perfect efficiency of the filter by using the special maintenance kit, containing cleaning liquid and spray lubricant (see the "Related Products" section) at the bottom of this page)
