Description

K&N Universal Rubber Air Filter 20 Deg Angled 2-7/16" Flange | RU-1750

Boost airflow and performance with the K&N Universal Round Air Filter (RU-1750). Features a 20° angled 2-7/16" flange, washable design, and high filtration.

The K&N Universal Rubber Round Filter provides maximum airflow and superior filtration for custom engine setups.

Engineered for versatility, this clamp-on air filter features a 20-degree angled flange designed to navigate tight engine bays and offset intake paths. Constructed with oiled cotton gauze media, it captures harmful contaminants while improving engine horsepower and acceleration. Its ultra-strong, pliable rubber flange absorbs road vibrations and stretches up to 1/16" to fit slightly varying intake tubing sizes. Designed to be washable and reusable, this air filter delivers long-term durability and cost savings over disposable paper filters.

Best Uses

  1. Custom Engine Builds: Fits tight or non-standard engine bays that require a 20° angle intake clearance.
  2. Motorsports & Racing: High-airflow design ideal for race cars, karts, and off-road vehicles.
  3. Small Engine Equipment: Suitable for power generators, lawn tractors, and snowmobiles.
  4. Custom Air Intakes: Great for aftermarket intake systems needing a 2-7/16-inch inlet.

Features

  1. 20-Degree Angled Flange: Solves clearance issues in tight engine compartments.
  2. Pliable Rubber Base: Absorbs engine vibration and stretches up to 1/16 in (1.5mm) for a secure fit.
  3. Layered Cotton Gauze Media: Provides high airflow while maintaining top-tier dirt separation.
  4. Washable & Reusable: Easy to clean and re-oil for thousands of miles of service.
  5. Exact Fit Dimensions: Features a 2-7/16" Flange ID, 3-3/4" Outer Diameter, and 4" Height.

Benefits

  1. Improved Engine Power: Delivers increased horsepower and faster acceleration by reducing intake restriction.
  2. Long-Term Savings: Replaces single-use paper filters, reducing maintenance costs over time.
  3. Vibration Resistance: Flexible rubber base prevents loosening and seals tightly during high vibration.
  4. Versatile Fitment: Universal design adapts easily to custom intake setups and various equipment.
  5. Engine Protection: Premium filtration guards against harmful dirt and debris without choking air supply.
