The K&N RU-5321 Universal Clamp-On Air Filter is engineered for versatility and performance across a wide range of custom applications, from racing vehicles and snowmobiles to generators and industrial equipment. This high-flow filter provides a reliable solution for intakes where a standard factory airbox is no longer used, offering superior filtration and airflow capacity.

  • Durable Construction: Built with ultra-strong, molded pliable rubber flanges that absorb engine vibration and ensure a secure, leak-free attachment.
  • Flexible Fitment: The flange material is designed to be stretched up to 1/16 of an inch (1.5mm) to accommodate in-between sizes and unique intake tube diameters.
  • Washable & Reusable: Features K&N's signature oiled cotton gauze media, allowing the filter to be cleaned and re-serviced for extended life.
  • Versatile Application: Suitable for any equipment where the intake angle or offset diameter requires a clamp-on high-performance filter.
