Description

K&N Universal Clamp-On Air Filter: 4" Flange, 9.5" H Chrome Tapered

Boost horsepower and acceleration with the K&N Universal Round Tapered Air Filter. Features a 4" flange ID, 9.5" height, chrome top, and washable oiled cotton media.

Engineered to increase airflow and horsepower, the K&N Universal Clamp-On Air Filter is built for custom, high-performance applications. Designed with premium multi-layer oiled cotton gauze, this round tapered filter captures microscopic contaminants without choking off vital air supply to your intake system.

It features a durable 4-inch flexible rubber flange that absorbs engine vibration and clamps securely onto existing intake piping. Standing at 9.5 inches tall with a sleek, polished chrome top, it delivers maximum surface area for high-volume airflow while adding a show-ready aesthetic under the hood. Completely washable and reusable, this filter is built to last the lifetime of your vehicle with proper maintenance.

Best Uses

  1. Custom cold air intake setups and custom turbocharger/supercharger plumbing.
  2. Performance engine builds requiring high volumetric airflow across hot rods, muscle cars, and track vehicles.
  3. Replacement upgrade for stock restrictive air boxes on performance trucks, SUVs, and passenger cars.

Features

  1. High-Flow Oiled Cotton Media: Multi-layered pleated cotton engineered to increase airflow up to 50% compared to disposable paper filters.
  2. Flexible Molded Rubber Flange: Strong, pliable rubber flange absorbs engine vibration and ensures a airtight, secure fit onto a 4-inch intake tube.
  3. Polished Chrome Top Cap: Corrosion-resistant chrome top provides structural rigidity while giving your engine bay a clean, custom look.
  4. Washable & Reusable Design: Fully cleanable with a K&N Recharger kit, allowing the filter to be serviced repeatedly for long-term use.
  5. Deep Pleated Construction: High pleat count maximizes overall surface area to maintain continuous airflow between service intervals.

Benefits

  1. Increased Horsepower & Acceleration: Reduces intake restriction, allowing your engine to draw in cooler, denser air faster for noticeable throttle response gains.
  2. Cost-Effective Long Term Savings: Replaces disposable paper filters, eliminating the need to buy new air filters every servicing cycle.
  3. Superior Engine Protection: Advanced filtration design traps dirt, dust, and microscopic debris to safeguard internal engine components.
  4. Easy Clamp-On Installation: Installs in minutes with the included heavy-duty hose clamp—no special tools required.
  5. Extended Service Intervals: Holds significant amounts of dust before requiring cleaning, capable of running up to 50,000 miles between services under normal highway driving conditions.
