YA-4510 filter was designed for the 2010 to 2013 Yamaha YZF450F. The filter is washable, and reusable.  It's designed to improve the motorcycle's power and torque. 

When changing to this filter, most will notice you can ride longer before needing to service the filter due to its depth loading ability that allows for more dirt to build up on the filter before significantly impacting air flow.
