Uni Filter Air Filter for Yamaha (NU-2221ST)

Improve intake protection and maintain dependable airflow with the UNI FILTER NU-2221ST Air Filter for Yamaha. Designed as a direct-fit replacement for the stock airbox, this reusable filter installs like an OEM component while helping stop dirt and debris before they reach the engine. Its washable construction lets you clean, re-oil, and reuse the filter indefinitely when properly maintained, making it a practical choice for regular riding and demanding off-road conditions.
The two-stage foam design separates for thorough cleaning and supports maximum airflow after servicing. UNI FILTER’s Ultra Seal grease groove on the sealing surface helps create a secure barrier between the filter and airbox, reducing the chance of contaminants bypassing the filter. Grease-cutting dishwashing detergent can be used to remove accumulated oil and dirt, followed by proper re-oiling before installation.
Made in the USA, the UNI FILTER NU-2221ST combines reusable convenience, effective engine protection, and consistent performance in a factory-style fit. Follow the manufacturer’s cleaning and oiling recommendations to preserve filtration efficiency and extend service life.
