Product Description

The K&N RU-1001 is a universal high-flow clamp-on performance air filter engineered to fit a wide range of automotive and custom applications. With a molded rubber flange designed for secure clamp attachment and slight flexibility in sizing, this filter offers increased airflow while maintaining excellent engine protection through its layered cotton gauze media.

Installation is flexible and straightforward: simply select the intake pipe or adapter that matches or is slightly smaller than the flange size, slide the RU-1001 on, clamp it firmly, ensure clearance inside the engine bay and you're ready to go. The pre-oiled media means the filter is ready right out of the box.

Because this is a universal-fit component rather than a vehicle-specific part, it is essential to confirm that your intake flange, pipe diameter, available space and clearance are compatible before purchase and installation. This product is not guaranteed to fit every vehicle or intake configuration without modification or adapter; fitment for specific makes/models/years is unconfirmed - buyers should measure and verify their setup prior to ordering.
