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. As shown in the photos it mounts below the dash panel, tucked out of the way. They are lightweight, hidden, and small. You can install it and forget it, knowing that it will keep the oil in your engine where it belongs.
2014 AND NEWER MODELS SHOULD HAVE THE AIS BLOCKED OFF FOR EASY INSTALLATION. Please see our AIS block off kit listing.
