Unlock the full potential of your 1000cc crossplane engine with the K&N Air Filter for Yamaha R1. Custom-engineered specifically for the 2009–2012 Yamaha YZF R1, this premium drop-in panel filter is designed to achieve high, virtually unrestricted airflow while providing the exceptional engine protection your sportbike needs.

Unlike standard restrictive paper filters, K&N uses multiple layers of woven cotton gauze media treated with a specially formulated grade of oil. This combination creates a tacky, highly efficient filtering grid that traps dirt and debris without choking your intake tract. The filter fits flawlessly directly inside your original equipment manufacturer (OEM) factory air box without any cutting, fitting, or fuel management modifications required. It comes pre-oiled from the factory and is ready to install out of the box.
