Product Description

The K&N KA-9098 is a high-flow replacement air filter engineered specifically for the Kawasaki ZX-9R (1998-2003). It replaces the stock air filter element with a pleated cotton-gauze media design that allows greater airflow while maintaining strong filtration and engine protection. This results in improved engine breathing, sharper throttle response, and potential performance benefits - especially under spirited riding or when paired with exhaust or tuning upgrades.

Installation is straightforward: KA-9098 fits directly into the stock airbox using an application-specific sealing bead, requiring no modifications or tuning for standard engine configurations. The filter comes pre-oiled and ready to ride. Because it is washable and reusable, it offers long-term cost savings and reduced maintenance compared to disposable filters - making it an excellent upgrade for ZX-9R owners who value both performance and durability.
