K&N 98-06 Honda CBR600 Hornet/04-06 CBF500/CBF600/CB600S/05 CBF600F Replacement Air Filter

K&N Engineering has been making performance air filters for over 40 years, and they're known for their high-flow cotton gauze designs. This HA-6098 filter is a direct replacement for your stock air filter on the 2004 and 2006 Honda CB600F 599. It's built to offer less restriction than a standard paper filter, which can help your engine breathe a little easier and potentially improve horsepower and torque.

The filter uses multiple layers of woven cotton gauze media that are pleated to give you a large filtration area. This design not only helps capture dirt effectively but also keeps airflow restriction low, meaning you get good engine protection without sacrificing performance. Because it's washable and reusable, you can clean it and use it again, which is a nice benefit for long-term maintenance. It comes pre-oiled and ready to install right out of the box.
