About MWR Air Filters

Jonathan Rea uses MWR air filters
MWR airfilters are specific performance foam airfilters for motorcycles, which are  handmade in the Netherlands. MWR airfilters are made of top quality materials (FR (Fire Resistant) Foam , stainless steel and aluminium). Unlike all other foam filters MWR airfilters are made entirely from MWR's special Fire Resistant (FR) foam.
MWR airfilters are continuously developed and improved trackside with MWR supported teams around the world - we have shared in 7 WSBK Titles with Kawasaki Racing Team and riders Tom Sykes and Jonathan Rea.
MWR airfilters are not just copies of the OEM filter but in fact specific designs to enhance the performance in the best possible way for your bike and to also offer the best possible protection from dirt and dust for your engine. 
Due to MWR airfilters being entirely constructed from foam and having no rubber mountings or mouldings MWR are able to utilise nearly 100% of the available area as filter element. Once again this helps improve air flow and increase performance.
To help protect your engine MWR has specifically made biodegradable airfilter oil. This MWR filter oil is made in the Netherlands and is completely biodegradable not only protecting the environment but also your engine either for heavy duty (off road) use or for long term normal (road/race) usage. This biodegradable filter oil is also completely fire proof.
All MWR filters are shipped out pre-oiled and ready to install.
Be sure to read our page on the different types of MWR air filters. The specifications of each type of MWR airfilter are very different, and each airfilter is specifically tailored to your application.
