Product Description

The K&N RU-1009 is a premium universal clamp-on high-flow air filter designed for vehicle applications where a 6-inch inlet flange and compatible housing exist. Its washable and reusable cotton gauze media increases airflow while offering superior filtration to protect the engine.

Installation is smart and straightforward: slide the filter onto a compatible intake pipe or adapter with a ~6" flange, secure with a clamp, ensure proper clearance in your engine bay, and you're ready. The unit is pre-oiled and ready to perform out of the box.

Because this unit is universal in design - not tied to a specific vehicle make/model/year/engine - it's essential to verify your intake flange diameter, intake pipe diameter, clearance and mounting orientation before purchase. Fitment lists for specific vehicles and through-2025 checks are unconfirmed for this part.
