Product Details

This is a K&N direct-fit replacement air filter, designed for a range of Yamaha YFZ450 and YFZ450R models from 2004 through 2025. If you ride in dusty conditions or at high altitudes, this filter can help keep your engine running cleanly and efficiently. It's built to provide clean carburetion, which is especially important when you're out on the trail or track.

K&N uses multiple layers of woven cotton gauze media to create a large filtration area. This means it can capture a lot of dirt and debris before needing service, offering long intervals between cleanings. Because it's washable and reusable, you can clean it and put it right back in, saving you money over time compared to disposable filters. Generally, you won't need to make any fuel management changes to see improved performance with this filter installed.

This filter is designed to fit directly into your OEM air box, with a specific sealing bead to ensure it sits properly. It's pre-oiled and ready to install, so you can get back to riding quickly.
