K&N Universal Clamp-On Air Filter 2-1/16in Flange | 3-1/2in OD | 4in Height

Upgrade your engine’s airflow with the K&N Universal Clamp-On Air Filter (2-1/16 in Flange). Washable, reusable, and built for maximum horsepower and torque gains.

Engineered for peak engine efficiency, the K&N Universal Clamp-On Air Filter delivers class-leading airflow without sacrificing filtration protection. Designed with a 2-1/16 in (52mm) flexible flange, a 3-1/2 in (89mm) outer diameter, and a compact 4 in (102mm) height, this versatile filter is built for custom intakes, racing setups, small engines, and tight engine bays.

Unlike restrictive, disposable paper filters, this high-flow air filter uses multiple layers of premium, pre-oiled cotton gauze media sandwiched between wire mesh screens. This advanced construction allows up to 50% more air to flow into your intake system, yielding noticeable improvements in horsepower, acceleration, and throttle response.

Equipped with a molded, ultra-durable rubber flange that absorbs vibration and ensures a secure, leak-free seal, it installs in minutes using the included heavy-duty stainless steel clamp. Fully washable and reusable, this K&N filter is designed to last the life of your vehicle—making it a cost-effective, eco-friendly upgrade for automotive and powersports enthusiasts alike.

Best Uses

  1. Small Engine & Powersports Vehicles: Motorcycles, scooters, ATVs, and snowmobiles.
  2. Racing & Custom Tuning Projects: Ideal for custom air intake builds, race cars, and vintage carburetor setups.
  3. Industrial & Outdoor Equipment: High-performance air filtering for generators, tractors, and lawn power equipment.
  4. RC & Hobbyist Vehicles: Radio-controlled cars and custom motorized builds requiring a 2-1/16" flange intake.

Features

  1. High-Flow Oiled Cotton Media: Engineered with 4 layers of pleated cotton gauze treated with a specialized tacking agent to capture airborne contaminants while maximizing airflow.
  2. Pliable Molded Rubber Flange: Ultra-strong rubber construction absorbs engine vibrations and stretches up to 1/16" (1.5mm) to accommodate slightly varying intake tube sizes.
  3. Washable & Reusable Design: Easily cleaned using K&N cleaning kits, offering a sustainable alternative to single-use disposable paper filters.
  4. Clamp-On Precision Fit: Includes a heavy-duty worm-gear hose clamp for easy, bolt-free mounting on custom air intakes.
  5. Compact Dimensions: Specific size profile featuring a 2-1/16" (52mm) inside diameter flange, a 3-1/2" (89mm) base outer diameter, and a 4" (102mm) overall height.

Benefits

  1. Enhanced Engine Performance: Reduces intake restriction to help increase horsepower, torque, and throttle response.
  2. Long-Term Cost Savings: Eliminates the ongoing cost of buying disposable filters over time.
  3. Superior Filtration Efficiency: Traps up to 99% of harmful dust and airborne particles to protect critical internal engine components.
  4. Eco-Friendly Upgrade: Helps reduce overall landfill waste by providing a filter that lasts for the life of your equipment.
