The K&N RU-3250 Universal Tapered Air Filter is engineered to provide high-flow performance for a broad range of custom intake applications, including racing vehicles, generators, tractors, and snowmobiles. Built with K&N’s signature oil-impregnated cotton media, this filter is fully washable and reusable, offering a sustainable alternative to disposable paper elements.

The filter features an ultra-strong, molded pliable rubber flange designed to absorb engine vibration for a secure, durable mounting point. This versatile flange material can stretch up to 1/16 of an inch (1.5mm) to accommodate minor variances in intake tube sizing. The tapered design allows for maximum surface area in constrained engine bays while maintaining high-velocity airflow.
