Product Description

The K&N RU-4700 High-Flow Replacement Air Filter is engineered as a performance element for compatible K&N 69 Series cold air intake systems that require this specific filter size. Constructed with multi-pleat oiled cotton gauze media, the RU-4700 increases airflow compared to many restrictive stock paper filters while still capturing contaminants to protect the engine. The round tapered shape and molded rubber flange ensure a secure fit in intake systems that specify this filter profile.

Washable and reusable, this filter can be cleaned and re-oiled multiple times instead of replaced, providing long-term value and reducing waste compared to disposable alternatives. The drop-in design makes installing or replacing the filter simple and straightforward, helping maintain optimized intake performance over time. Ideal for performance intake systems where the RU-4700 is the specified replacement element, this filter supports better throttle response and efficient breathing without sacrificing engine protection.
