Product Description

The K&N RU-1020 is a premium universal clamp-on high-flow air filter designed for vehicle applications where a 6-inch inlet flange is used or where aftermarket intake piping allows match. Its washable and reusable cotton gauze media offers both improved airflow and strong engine protection compared to standard disposable filters.

Installation is straightforward: slide the RU-1020 onto a compatible intake pipe or adapter with the appropriate flange size, secure it with a clamp, ensure proper clearance in the engine bay, and you're ready to go. The pre-oiled media means the filter is prepared for immediate use.

Because this is a universal-fit component rather than one tied to a specific vehicle make/model/year/engine, it is essential to verify the intake pipe diameter, flange size, orientation, and available space before purchasing. Compatibility with all vehicles through 2025 is unconfirmed - please check your application for proper fitment.
