Its universal configuration accommodates air intakes with varying angles and offset diameters, making it a practical replacement or performance upgrade where a standard application-specific filter is not suitable.

Built with a durable, pliable molded rubber flange, the K&N RU-3600 helps absorb vibration while providing a secure connection to the intake. The flange can stretch slightly to accommodate minor variations between sizes, supporting a reliable fit across compatible intake systems. The washable and reusable filter element can be cleaned and serviced repeatedly with the appropriate K&N maintenance products, helping reduce the need for frequent replacement filters. An optional K&N 25-3900 Air Filter Foam Wrap and 99-5000 Filter Care Service Kit Aerosol are associated products.
