Product Description

The RC-5106 Universal Clamp-On Air Filter from K&N is a versatile, high-flow filter built to support a wide range of custom intake systems - from performance builds and racing setups to aftermarket or non-OEM airboxes. Its round-tapered cone shape and large base offer substantial filtration surface area and airflow capacity, helping engines breathe more freely while maintaining effective filtration. The molded rubber flange provides a secure, vibration-resistant clamp-on mounting, and its ability to stretch slightly helps accommodate slight flange size variances.

Because the filter is washable, reusable, and pre-oiled, it offers long-term value and convenience compared to disposable filters. Installation is straightforward: simply clamp onto a compatible intake tube, ensuring adequate clearance and proper orientation. This makes RC-5106 a solid choice for tuners, custom builds, or any vehicle requiring a universal, high-flow air filter upgrade rather than a vehicle-specific drop-in replacement.
