Product Description

The K&N RF-1041 Universal Rectangular High-Flow Air Filter is built to deliver enhanced airflow and long-term value for a variety of intake applications where a 10" x 4.25" panel filter is required. Constructed with layered oiled cotton gauze media and expanded pleats, this filter offers significantly increased surface area compared to conventional paper filters, helping improve engine breathing, throttle response, and performance while still capturing harmful contaminants.

Because the RF-1041 is washable and reusable, it can be cleaned and re-oiled instead of replaced, reducing waste and lowering ownership costs over time. Its universal rectangular design makes it suitable for many custom intake setups, aftermarket airboxes, and performance applications - but always measure your specific intake opening to confirm compatibility before installation. This durable filter is an excellent choice for enthusiasts and builders looking for a flexible, high-flow air filtration solution.
