The K&N RU-5295 is a round, tapered, cotton-gauze universal clamp-on air filter for custom intake builds where no direct-fit element exists. The manufacturer's High-Flow line is designed to increase horsepower and acceleration, and the manufacturer rates overall efficiency up to 99%. Its 6-inch flange, 7-1/2-inch base, and 20-1/8-inch height suit tall, large-diameter intake housings. Because the media is washable, you can clean and re-oil it over its service life instead of replacing it, and the manufacturer backs it with a one-year limited warranty.
This is a universal part, not a vehicle-specific one, so measure your intake tube's diameter and the clearance around the mounting point before ordering. The flange is a centered design, and the manufacturer describes its rubber flanges as malleable, which helps them seat over a tube and hold under a clamp.

The manufacturer describes it as a clamp-on, washable, and reusable air filter, so it is meant to be cleaned and re-oiled rather than thrown away.
The manufacturer lists a re-oiling amount of 5.15 oz (152 ml) for this filter.
The manufacturer provides a one-year limited warranty on this filter.
Installation is a basic bolt-on task: slide the malleable flange onto the intake tube, secure it with a clamp, and confirm it is seated before you close the airbox. Cleaning and re-oiling are the main maintenance tasks. Per the manufacturer's guidance, rinse the filter with cool, low-pressure water from the clean side outward, then let it dry naturally before oiling. Apply the oil evenly along the crown of each pleat, and if oil drips, let it settle and wipe the excess from the filter frame before reinstalling. Use K&N's own cleaner and oil, since the manufacturer's guidance is written around its products.
