Maximize Airflow with Uni Filter NU-4049

The Uni Filter NU-4049 is the gold standard for riders looking to improve engine breathing and overall power output. Featuring a signature dual-stage foam design, this air filter traps fine dust and debris in the outer layer while the inner layer provides high-volume airflow to your engine.
