Product Description

The K&N RU-1008 is a premium universal clamp-on high-flow air filter engineered for custom and performance intake systems. With a 4.50" flange size, it's ideal for aftermarket applications where a direct vehicle-specific filter may not exist. Its washable and reusable cotton gauze media improves engine airflow while providing strong filtration protection.

Installation is straightforward: slide the RU-1008 onto a compatible intake pipe or adapter (that matches or is slightly smaller than the flange), secure with a clamp, ensure proper engine bay clearance, and you're ready to go. Because it is pre-oiled, no extra preparation is required before use.

Since this is a universal-fit component rather than a part tied to a specific vehicle make/model/year/engine, it is essential to verify the intake flange diameter, available clearance, and mounting orientation before purchasing. Fitment through 2025 (for specific vehicles) is unverified - ensure your application is compatible before installation.
