Product Details

The chrome-plated steel base and top on this K&N air filter mean it's built to last, even in tough off-road conditions. This filter is designed to mount directly into rubber grommets on valve covers, making it a straightforward replacement for your Honda CR125R, CR250R, CR450R, or CR480R from the early 80s. It uses a non-woven synthetic media that offers a great balance of high airflow and solid filtration, which is crucial for keeping your engine running cleanly, especially at higher altitudes or in dusty environments.

Because this K&N filter is washable and reusable, you can clean it and use it repeatedly, which is a practical benefit for any rider. The zinc-plated tube is designed to push in and clamp onto tubing where venting is needed, offering a secure fit. This means you can expect clean carburetion without needing to make major jet changes, simplifying maintenance and ensuring your bike performs reliably on the trail.
