Description

K&N Universal Clamp-On Air Filter | 2-7/8" Flange, 4" OD, 6" Height (RU-1620)

Shop the K&N Universal Rubber Air Filter (2-7/8" Flange, 4" OD, 6" Height). High-flow, washable, and reusable design built to increase horsepower and acceleration.

The K&N Universal Clamp-On Air Filter (RU-1620) is engineered to increase airflow, improve horsepower, and deliver outstanding filtration. Constructed with ultra-strong molded pliable rubber flanges, this filter absorbs engine vibration while ensuring a tight, leak-free seal. The pliable flange can stretch up to 1/16 of an inch (1.5mm) to accommodate intermediate intake tube sizes for a seamless fit.

Featuring K&N's signature oiled cotton gauze filter media, it offers high-capacity dirt holding and long service intervals. Unlike disposable paper filters, this filter is fully washable and reusable, making it a durable performance upgrade across various custom and replacement setups.

Best Uses

  1. Custom Intake Systems: Ideal for custom cold air or short ram air intake builds needing a 2-7/8 inch flange diameter.
  2. Motorsports & Racing: High-flow protection suited for racing vehicles and track applications where maximum airflow is crucial.
  3. Power Equipment: Great for generators, tractors, and utility equipment requiring enhanced air filtration.
  4. Powersports & Recreation: Works with snowmobiles, ATVs, and radio-controlled cars using matching flange measurements.

Features

  1. Pliable Rubber Flange: Molded rubber construction absorbs engine vibration and allows up to 1/16" (1.5mm) stretch for a secure fit on intermediate sizes.
  2. Washable & Reusable Design: Premium oiled cotton media allows you to wash, re-oil, and reuse the filter for extended durability.
  3. High-Flow Cotton Media: Designed with multi-layered, oiled cotton gauze to maximize airflow while capturing dirt particles.
  4. Universal Clamp-On Fitment: Features a 2-7/8" inner flange diameter, 4" outer diameter, and 6" height for easy clamp-on installation.
  5. Durable Molded Structure: Built with heavy-duty top plates and sturdy wire mesh to maintain structural shape under high intake pressure.

Benefits

  1. Increased Horsepower & Acceleration: Designed to allow higher airflow, helping engines draw in cool air more efficiently to improve performance.
  2. Cost-Effective Savings: Eliminates the need for frequent disposable paper filter replacements over the life of your equipment.
  3. Vibration Absorption: Flexible rubber flange dampens engine vibrations to prevent the intake tube connection from loosening.
  4. Superior Engine Protection: Provides high filtration efficiency to shield your engine against harmful dirt and debris.
  5. Easy Installation: Clamp-on design ensures quick mounting directly onto intake tubes or air horns without complicated modifications.
