38 Motorsports G6 YFZ450R/YFZ450X oil blow by breather box for 2009 and newer fuel injected YFZ.
Replaces your stock box that leaks and/or doesn't work well, or the ltr or aftermarket breathers that are just in the way. As with everything we offer they have been tested extensively, these things work! They work well with large fuel tanks. A
