Product Description

The K&N RU-5302 is a universal round-tapered air filter designed to serve a wide variety of custom intake applications - from modified street vehicles to performance builds, off-road rigs, and custom installations. Rather than targeting a specific vehicle, this filter uses a 5.0-inch flange with a flexible molded rubber base, allowing it to clamp onto compatible intake tubes or housings with relative ease. The cotton-gauze media provides a balance of high airflow and effective filtration, helping engines breathe more freely while still trapping contaminants.

Thanks to its washable and reusable design, the RU-5302 offers long-term value compared to disposable filters. It arrives pre-oiled and ready for installation, which makes it a convenient choice for enthusiasts upgrading or customizing their air intake setup. Because it's universal, proper fitment depends on matching intake tube diameter and ensuring sufficient clearance - so it's best suited for custom or aftermarket intake systems rather than OEM-specific airboxes.
