Boost performance with the K&N Universal Oval Clamp-On Air Filter (RU-1500) featuring a 2.75" flange. Premium washable cotton media increases airflow and power.

The K&N Universal Oval Clamp-On Air Filter is engineered to increase horsepower and acceleration by maximizing air flow to your engine. Built with 4 layers of premium cotton gauze treated with a specialized tacking agent, it captures harmful contaminants without restricting intake performance. Its ultra-strong, flexible rubber flange absorbs engine vibration and stretches up to 1/16 of an inch for a snug, leak-free seal.

  3. Specialty Equipment: Ideal for generators, tractors, snowmobiles, and small engines.

Features

  1. 4-Layer Cotton Gauze Media: Features oiled, multi-layer cotton mesh designed to filter out dust and dirt efficiently.
  2. Pliable Molded Flange: Absorbs engine vibration and stretches up to 1/16 in (1.5mm) for precise fitting.
  3. Clamp-On Design: Ships pre-oiled and ready to install with an included hose clamp for quick attachment.
  4. Oval Shape Dimensions: Measures 6-1/4" Length x 4" Width x 5" Height with a 2-3/4" (2.75 in) Flange ID.
  5. Washable & Reusable: Designed to be cleaned and re-oiled for long-lasting, repeatable service life.

Benefits
