Replacement Air Filter

The K&N YA-1906 is a high-flow, washable, and reusable replacement air filter engineered for specific Yamaha motorcycle models from 2006-2017. Its construction utilizes four to six sheets of cotton gauze layered between aluminum wire mesh, pleated and oiled to maximize filtration capabilities and performance. This design originates from K&N's development in desert motocross racing, aiming to deliver enhanced airflow, increased horsepower, and improved acceleration. The filter's unique medium was developed to achieve virtually unrestricted air flow while upholding filtration levels essential for engine life. K&N states this air filter allows dramatically more air into the engine, contributing to enhanced performance and protection from dirt and dust throughout the life of the motorcycle. The 4.375-inch width makes it suitable for both 2- and 4-wheel applications where specified. Customers report noticeable performance gains, including mid-range power increases, and appreciate the easy installation and maintenance. While generally well-regarded as a worthwhile upgrade, some feedback indicates potential fitment issues on specific models and occasional quality control concerns.
