Description

K&N Universal Blue Air Filter - Chrome Round Tapered | 4in Flange x 5.5in H

Boost airflow and engine power with the K&N Universal Round Tapered Blue Air Filter. Features a 4in flange ID, chrome top, and washable oiled cotton media.

Engineered to deliver high airflow while maintaining exceptional filtration, the K&N Universal Clamp-On Air Filter is a premium performance upgrade for custom applications. Built with a distinctive blue oiled cotton gauze media sandwiched between wire mesh layers, this round tapered filter maximizes surface area to feed cool, clean air into your intake system.

It comes equipped with a polished chrome top cap for a show-quality engine bay look and a durable molded rubber 4-inch flange that absorbs engine vibration and clamps securely onto intake piping. Designed as a permanent replacement for disposable paper filters, this filter is washable, reusable, and built to withstand harsh driving conditions without compromising airflow or engine protection.

Best Uses

  1. Custom cold air intake systems requiring a 4-inch outer diameter intake tube fitment.
  2. Performance engine builds, hot rods, race cars, and street machines with tight clearance around the air intake.
  3. Off-road trucks, SUVs, and custom vehicle builds needing durable high-filtration air intake components.

Features

  1. Oiled Blue Cotton Media: Multi-layered oiled cotton gauze designed for maximum air velocity and high filtration capacity.
  2. Chrome Top Cap: Features a high-luster polished chrome end cap for superior durability and engine bay styling.
  3. Flexible Molded Flange: Ultra-strong 4-inch inner diameter pliable rubber flange that stretches up to 1/16-inch for slight fitment variations and dampens vibration.
  4. Round Tapered Design: Tapered profile maximizes air intake surface area within tight engine compartments.
  5. Washable & Reusable: Fully cleanable with a K&N filter care kit, eliminating the need to buy replacement paper filters.

Benefits

  1. Increased Horsepower & Acceleration: Reduces air intake restriction to let your engine draw in more oxygen for improved power output.
  2. Engine Protection: Captures fine contaminants without restricting overall airflow, shielding internal components from harmful debris.
  3. Cost-Effective Long-Term Solution: Designed to last the life of your engine, reducing ongoing maintenance costs.
  4. Show-Ready Aesthetics: High-contrast blue media combined with a mirror-finish chrome cap instantly elevates your engine compartment's appearance.
  5. Easy Clamp-On Installation: Comes pre-oiled and ready to mount directly onto matching intake tubing using the included clamp.
