YFZR breather box. Finally releasing these to the public! 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 I offer they get tested extensively. These boxes have been in testing for nearly two years. I have yet to blow out one drop of oil, or have any pressure related issues. These things work! As shown in the photos it mounts above the radiator tucked out of the way. It will not fit with an aftermarket fuel tank. It does work with the larger capacity radiators I have tried it on. Pricing is $135 shipped in the US. International shipments will be more. I have a version for 09-13 and for 14+ model years. 14+ needs to have the AIS removed. 09-13 with spal fan needs the fan mount modified. Message me for details, questions, or to purchase.
I have a few in stock.... 3 for 2014+ model years, and 3 for 09-13 model.
