Description

K&N Universal Rubber Air Filter 2-3/4" Flange | 6" Base

Boost performance with the K&N Universal Clamp-On Air Filter (RU-4870). Features a 2 3/4" flange, washable design, high-flow media, and extreme durability.

The K&N Universal Rubber Air Filter (RU-4870) is engineered to increase horsepower and acceleration by allowing significantly more airflow into your engine than traditional disposable paper filters. Constructed with premium oiled cotton gauze media layered between wire mesh screen, it delivers outstanding filtration efficiency while retaining low airflow restriction.

Designed for custom and universal applications, this filter features an ultra-strong, pliable rubber flange that absorbs engine vibration and allows secure attachment to intake piping. The flexible rubber construction can stretch up to 1/16 of an inch (1.5mm) to fit intermediate sizes seamlessly. Fully washable and reusable, this K&N filter is designed to last for the life of your vehicle or equipment.

Best Uses

  1. Custom Engine Builds & Air Intakes: Ideal for custom cold air intakes, turbo setups, and engine swaps requiring a 2.75-inch inlet flange.
  2. Motorsports & Racing Vehicles: Suitable for high-RPM environments where maximum airflow is required without sacrificing filtration.
  3. Off-Road & ATV/UTVs: Great protection for off-road environments where dust and dirt filtration are essential.
  4. Small Engines & Power Equipment: Frequently utilized on generators, tractors, snowmobiles, and custom project builds.

Features

  1. High-Flow Oiled Cotton Media: Uses multi-layered, oiled cotton gauze designed to maximize airflow while offering reliable dust retention.
  2. Pliable Molded Rubber Flange: Ultra-strong, flexible rubber flange absorbs engine vibration for a firm, non-slip grip.
  3. Stretchable Flange Design: Flange material can stretch up to 1/16 in. (1.5mm) to accommodate slightly varied intake tube dimensions.
  4. Washable & Reusable Filter: Designed to be cleaned and re-oiled using a K&N Recharger Kit, eliminating the need for frequent replacements.
  5. Durable Wire Mesh Shield: Reinforced with heavy-duty coated aluminum wire mesh to retain its structural shape under heavy engine suction.

Benefits

  1. Increased Horsepower & Torque: Superior airflow reduces intake restriction, enabling noticeable horsepower gains and throttle response.
  2. Cost-Effective Long-Term Solution: Washable design means you don't need to purchase disposable paper filters repeatedly.
  3. Engine Protection: Captures microscopic contaminants to shield engine components from internal wear and damage.
  4. Custom Fit Flexibility: Universal sizing makes it easy to install on custom intakes, race cars, and aftermarket projects.
  5. Eco-Friendly Choice: Reusing one air filter reduces waste sent to landfills compared to single-use alternatives.
