MWR Race Air Filter for Yamaha R3 2015+
To make more power from the same motor, you have to flow more fuel and more air. The thin, lightweight, dome shaped MWR foam race air filter flows more air than any other filter on the market. Because this is a thin foam style race filter, you must clean it and oil it regularly to protect your motor. At a minimum, clean and oil your MWR filter a few times per year, but ideally, clean and oil your filter after every race weekend.
Use only MWR brand filter cleaner and filter oil.
