Description

K&N RU-0600 Universal Air Filter | 2.25" Flange, 3.5" OD, 4" Height

Boost performance with the K&N RU-0600 Universal Air Filter. Features a 2-1/4" pliable rubber flange, 3-1/2" outer diameter, 4" height, and washable oiled cotton design.

The K&N Universal Clamp-On Air Filter (Part # RU-0600) is engineered to boost overall engine output by delivering up to 50% more airflow than standard paper filters. Constructed with multi-layered oiled cotton gauze media, it traps dirt and dust particles while maximizing performance and acceleration.

This round straight performance filter features a 2.25-inch (57 mm) inner diameter flange, a 3.5-inch (89 mm) outer diameter, and stands 4 inches (102 mm) in total height. Built with ultra-strong, pliable molded rubber flanges, it effectively absorbs engine vibrations and can stretch up to 1/16 of an inch (1.5 mm) for a custom, secure fit on intermediate sizes. Fully washable and reusable, it is designed to last the lifetime of your machine with proper maintenance.

Best Uses

  1. Custom Intake Systems: Ideal for custom-built automotive air intakes requiring a 2-1/4" mounting flange.
  2. Powersports & Motorcycles: Suitable for custom motorcycles, ATVs, and snowmobiles.
  3. Racing Applications: Great for track cars, go-karts, and off-road racing rigs needing high airflow.
  4. Equipment & Small Engines: Fits tractors, generators, and small industrial engines requiring clean, efficient intake filtration.

Features

  1. High-Flow Cotton Gauze Media: Engineered with multiple layers of premium oiled cotton to maximize airflow while delivering up to 99% filtration efficiency.
  2. Pliable Molded Rubber Flange: Strong, flexible 2.25" flange absorbs heavy vibrations and stretches up to 1/16 in (1.5 mm) for a secure fit.
  3. Washable & Reusable Design: Fully washable using K&N cleaning kits to perform like new for years.
  4. Precision Dimensions: Compact round straight profile featuring a 3.5" outer diameter and 4" height to fit tight engine bays.
  5. Clamp-On Convenience: Includes a pre-installed clamp for simple, tool-free mounting directly onto intake tubing.

Benefits

  1. Enhanced Engine Performance: Delivers superior airflow to increase horsepower and acceleration.
  2. Cost-Effective Long Term: Eliminates the need to buy disposable paper filters over and over.
  3. Vibration Dampening: Molded rubber connection isolates the filter body from engine movement, preventing fatigue and damage.
  4. Flexible Fitment: Stretches slightly to compensate for small manufacturing variances in intake tube sizes.
  5. Eco-Friendly Choice: Reusable design keeps disposable filters and unnecessary packaging waste out of landfills.
