Product Description

The K&N YA-6601 is a high-flow, washable replacement air filter designed for the Yamaha Raptor 660R (models from 2001-2005). It features pleated cotton gauze media across multiple layers, offering a large filtration surface and excellent dirt-holding capacity.

Built for off-road riding, it fits directly into the OEM airbox with a custom sealing bead for a tight, leak-free install. The washable and reusable design means you can clean and re-oil the filter instead of replacing it frequently, saving money in the long run. Plus, most stock applications don't need any fuel tuning, making this a plug-and-play upgrade for better airflow and lasting performance.
