Description

K&N Universal Clamp-On Air Filter 6in FLG x 7-1/2in B

Boost airflow and horsepower with the K&N Universal Clamp-On Air Filter (Part # RU-5173). Featuring a 6" flange, 7.5" base, 5.875" top, and 6" height, this washable filter delivers top engine protection.

The K&N Universal Clamp-On Air Filter (Part # RU-5173) is engineered to maximize airflow and increase horsepower across custom automotive and racing applications. Designed in a round tapered cone shape, it features a 6-inch inside flange diameter, 7.5-inch base diameter, 5.875-inch top diameter, and a 6-inch overall height.

Built with multiple layers of premium oiled cotton gauze media encased between wire mesh screens, this high-flow filter provides superior filtration efficiency while drastically reducing airflow restriction compared to standard paper filters. Its ultra-strong, pliable rubber flange absorbs engine vibration and can stretch up to 1/16 in. (1.5mm) to accommodate minor sizing variations on intake tubing. Fully washable and reusable, this air filter is designed to last the life of your vehicle.

Best Uses

  1. Custom Cold Air & Short Ram Intakes: Fits custom intake piping with a 6-inch outer diameter inlet tube.
  2. Race & High-Performance Vehicles: Ideal for street performance builds, track cars, and drag racers needing unrestrictive, high-volume airflow.
  3. Turbocharged & Supercharged Builds: Provides high airflow capability required by forced-induction engines.
  4. Specialty Equipment: Great for custom trucks, tractors, generators, or off-road vehicles requiring heavy-duty filtration in compact spaces.

Features

  1. High-Flow Oiled Cotton Media: Made with layered premium cotton gauze treated with a specialized tacking agent to trap dirt while maximizing airflow.
  2. Flexible Molded Rubber Flange: Constructed with durable rubber that absorbs engine vibration and stretches up to 1/16 in. (1.5mm) for a tight fit.
  3. Specific Precision Dimensions: Features a 6" flange ID, 7.5" base OD, 5.875" top OD, and a 6" overall height for precise engine bay placement.
  4. Pre-Oiled & Ready to Clamp: Factory pre-oiled with K&N filter oil and includes a heavy-duty worm-gear clamp for instant installation out of the box.
  5. Washable & Reusable Construction: Can be cleaned and re-oiled repeatedly using a K&N Recharger kit rather than thrown away.

Benefits

  1. Increases Horsepower & Acceleration: High-flow design reduces air intake resistance, allowing the engine to pull in cooler, denser air for improved engine performance.
  2. Saves Money Over Time: Eliminates the continuous cost of buying replacement disposable paper filters.
  3. Exceptional Engine Protection: Multi-layer filtration guards your engine against fine dust, dirt, and road contaminants.
  4. Secure, Leak-Free Seal: Vibration-dampening rubber flange prevents air leaks and ensures the filter stays secured even under high RPMs or rough terrain.
  5. Environmentally Friendly: Reusable design prevents hundreds of disposable paper filters from ending up in landfills.
