MWR Racing WSBK Air Filter for '09-'14 Yamaha YZF-R1

The MWR “R” filter has consistently offered the best power overall compared with all other aftermarket sports filters, but now with the cooperation of several top teams (Kawasaki (KHI), MV Agusta, and other WSBK and MotoGP teams (that due to contractual agreements must remain nameless) they have developed a new style of airfilter called simply WSBK that increases the filter surface enormously.
