Description

The stock air filter on your CBR900RR restricts airflow and requires frequent replacement, cutting into both your performance and your budget. The UNI FILTER NU-4121 delivers measurably higher airflow while maintaining a precision fit to your stock airbox, giving you better throttle response without modification. With an indefinite service life, you'll simply clean and re-oil it—no more disposable filters.

Helps keep cool, works great!
