MWR Air Filters are built upon 2 decades of experience in developing and producing high performance air filters for road, race, and off road use.
This experience has been gained working with some of the biggest air filter companies in Europe in areas such as World MX, Dakar (bikes, cars and trucks), Moto GP, WSB, BSB, AMA and even Rallycross. The knowledge gained during this period was invaluable and led MWR to develop their range of performance foam filters.
The Performance (Standard) Filter
This filter is a direct performance upgrade from your bikes standard filter. Offering better airflow and protection than the original, this filter will (when maintained correctly) last the life of your bike, simply clean and re-oil once a year.
The HE (High Efficient) air filter for road & race bikes
The revolutionary HE Air filter increases power and reduces intake noise. Unlike any other sports filter all inlets will get the same quantity of air, regardless of the speed of the motorcycle or wind directions. This is because of the unique design of the Air Splitter Plate (see illustration to understand how the Air Splitter works) and how it evenly distributes air throughout the airbox. No different fuel-mappings between internal & external or front & rear cylinders are needed. Clean and re-oil once a year.
NOTE: For the best performance, Order two more of the Shortest velocity stack that comes in your Airbox from your local Yamaha dealer, and replace the two taller stacks.
