K&N Engineering designs and manufactures a wide variety of universal air filters for many different uses. Regardless of the shape or size, K&N probably has a universal air filter for your specific equipment needs.

K&N has released a new round tapered universal (cone) air filter, part number RU-5174. It was constructed with an ultra-strong pliable rubber flange which absorbs vibration and allows for secure attachment. K&N universal air filter flanges can stretch for up to 1/16 inch (1.5mm) to fit in-between sizes.

The RU-5174 is 5 in. (127 mm) in length with an outside base diameter of 6 inches (152 mm) and a rubber top that has an outside diameter of 5 in. (127 mm). The inside diameter of the flange is rather small at only 2.5 in. (64 mm). The flange length is 2 inches (51 mm) which allows plenty of room to clamp around many engine intakes. This universal air filter may be used for any application meeting these measurement requirements.

Because of its small flange diameter, the RU-5174 is ideal for smaller engines such as import cars with smaller intake tubes.

K&N Universal Air Filters are great for extended use in dirty and dusty conditions. The RU-5174, like all K&N Universal Filters, is a washable and reusable filter. It is designed to offer low restriction while providing excellent motor protection.
