Description

K&N Universal Rubber Air Filter | 2.5" Flange ID x 3.5" OD x 5" H

Boost airflow and performance with the K&N Universal Rubber Air Filter (2.5in Flange ID x 3.5in OD x 5in H). High-flow, washable, and reusable design. 

Engineered for versatile, high-performance applications, the K&N Universal Rubber Air Filter offers exceptional airflow while maintaining high filtration efficiency. Constructed with K&N’s signature layered, oiled cotton gauze media, this filter is designed to increase horsepower and torque by reducing air intake restriction.

It features an ultra-strong, pliable molded rubber flange designed to absorb engine vibrations and deliver a secure, leak-free clamp-on attachment. The flexible rubber construction allows the flange to stretch up to 1/16" (1.5mm) to accommodate minor variations in intake tube sizing. Washable, reusable, and built to last, this filter is an eco-friendly alternative to disposable paper filters.

Best Uses

  1. Custom cold air intake systems and aftermarket turbo/supercharger setups.
  2. Motorcycles, ATVs, dirt bikes, and snowmobiles requiring a 2.5-inch inlet.
  3. Go-karts, racing vehicles, and custom automotive engine swaps.
  4. Small engines, generators, tractors, and industrial power equipment.

Features

  1. Pliable Molded Rubber Flange: Dampens engine vibration and stretches up to 1/16" (1.5mm) for a tight, versatile fit on 2.5" intake tubes.
  2. High-Flow Cotton Gauze Media: Multi-layered oiled cotton captures dirt particles while maximizing clean airflow.
  3. Washable & Reusable: Designed to be cleaned and re-oiled using a K&N Recharger kit, eliminating the need for frequent replacements.
  4. Compact Dimensions: Precise 2.5" Flange ID, 3.5" Outer Diameter, and 5" Height to fit tight engine bays and custom enclosures.
  5. Clamp-On Design: Simple installation using standard hose clamps for immediate, secure attachment.

Benefits

  1. Improved Engine Output: Enhances horsepower and throttle response by minimizing intake airflow restriction.
  2. Long-Term Cost Savings: Reusable design saves money over time by replacing single-use paper filters.
  3. Superior Engine Protection: Provides excellent filtration efficiency to keep harmful dust, dirt, and debris out of the combustion chamber.
  4. Vibration Resistance: Molded rubber base resists cracking and prevents structural degradation under high-vibration conditions.
  5. Universal Adaptability: Versatile sizing accommodates a massive range of automotive, powersports, and industrial applications.
