Unlock the true performance potential of your motorcycle with the K&N Replacement Drop-In Air Filter (Part No. YA-3215), custom-engineered specifically for the 2015-2017 Yamaha YZF R3 (321cc). Built on over 40 years of precision American engineering, this high-flow panel filter serves as a direct upgrade to your restrictive factory paper element.

Unlike generic disposable filters, K&N utilizes multiple layers of premium woven cotton gauze media treated with a specialized grading oil. This advanced design creates a high-volume airflow path that optimizes acceleration and sharpens throttle response while maintaining exceptional filtration efficiency to block engine-damaging debris. Featuring an application-specific base seal and molded sealing bead, it locks perfectly into your factory air box for an airtight fit without requiring any fuel management modifications, ECU remapping, or specialized tools. It comes pre-oiled and ready to install right out of the box, backed by a No-Hassle Lifetime Limited Warranty.
