K&N has released a new round tapered universal air filter (RU-5172) with 6 ply material and deep pleats. This makes it a great choice for a custom application where maximum capacity and filtration are required. The K&N air filter is constructed with an ultra-strong pliable urethane flange, which absorbs vibration and allows for secure attachment. K&N universal air filter flanges can stretch up to 1/16 inch (1.5 mm) to fit in between sizes.

The RU-5172 is 7.938 inches (202 mm) in height with an outside base diameter of 9 inches (229 mm) and a rubber top that has an outside diameter of 7 inches (178 mm). The inside diameter of the flange is 4.875 inches (124 mm). The flange length is 1.25 inches (32 mm), which allows plenty of room to clamp around many engine intakes. It comes pre-treated with 5.75 oz. of K&N filter oil so it is ready to use.

K&N universal air filters are designed to provide increased airflow while providing excellent engine protection. The RU-5172, like all K&N universal air filters, is a washable reusable filter and warranted against defective material or workmanship for one year form the date of purchase with no mileage limitations.
