K&N 86-99 Yamaha YFM350FW Big Bear Air Filter

K&N Engineering is well-known for making performance air filters that help engines breathe better. This replacement air filter, part number YA-2597, is designed for a range of Yamaha off-road vehicles like the Big Bear, Timberwolf, and Kodiak. It's built to handle dirty and dusty conditions, ensuring your engine gets clean air even at higher altitudes, which helps keep your carburetion running smoothly.

This filter uses multiple layers of woven cotton gauze media, which offers excellent filtration while still allowing for high airflow. This means you can expect improved horsepower and acceleration without needing to make any fuel management modifications. The pleated media provides a large filtration area, leading to longer service intervals between cleanings. Plus, it's washable and reusable, so you can clean it and use it again, making it a solid option for extended off-road use.

Installation is straightforward as it's designed to fit directly into your OEM air box, with an application-specific sealing bead to ensure a precise fit. It comes pre-oiled and ready to ride, and is backed by a one-year limited warranty.
