Product Details
If you're heading out for some serious off-road riding on your Yamaha ATV, keeping your engine breathing clean air is crucial, especially in dusty conditions or at high altitudes. This K&N replacement air filter is built to handle that kind of use, ensuring your carburetion stays clean and consistent so you can focus on the trail.
This filter is made with multiple layers of woven cotton gauze media, which offers excellent filtration while still allowing for high airflow. Because it flows so well, you generally won't need to make any fuel management adjustments to see improved performance. Plus, it's designed to fit directly into your OEM air box with a specific sealing bead, so installation is straightforward. Being washable and reusable means you can clean it and use it again and again, making it a solid option for extended use.
This K&N filter is a popular choice for a range of Yamaha models, including the Bear Tracker, Big Bear, and Bruin. It's pre-oiled and ready to install right out of the box.
