UNI FILTER Replacement OEM Air Filter - Honda NU-4049

If you're running a Honda with the stock air filter, you're leaving performance on the table. The UNI FILTER NU-4049 delivers measurably higher airflow than OEM filtration while maintaining the same fit and compatibility—meaning better throttle response and engine efficiency without modification. Unlike disposable filters that need constant replacement, this washable design offers indefinite service life, saving you money and reducing waste over time.

The NU-4049 is engineered to drop into your stock airbox exactly like the original, so installation is straightforward. Simply clean it with dish soap when needed, re-oil, and you're back on the road. Made in the USA with proven filtration media, it's the upgrade serious Honda owners choose when they want reliable performance without compromise.
