K&N Universal Round Tapered Clamp-On Air Filter RU-5288 - 3in Flange ID x 6in Base x 4.625in Top x 3in Height

The K&N RU-5288 Universal Air Filter is a high-performance, clamp-on filtration solution designed for custom intake systems, racing vehicles, and industrial equipment. Utilizing K&N’s legendary oiled cotton media, this filter provides low restriction and high airflow to help engines breathe more efficiently. The pleated design offers a large surface area for extended service intervals even in dusty environments.

Built for durability and ease of installation, the RU-5288 features an ultra-strong, molded pliable rubber flange. This material absorbs engine vibration for a more secure attachment and can be stretched up to 1/16 inch (1.5mm) to fit slightly non-standard intake tube sizes. Because the filter is fully washable and reusable, it represents a long-term alternative to disposable paper filters.
