K&N High-Flow Universal Clamp-On Air Filter RU-3020 — 5 in Flange, 9 in Height

Designed to fit a broad range of vehicles and filtration needs, this washable and reusable air filter is built to let your engine breathe easier without the cost of frequent replacements. The media is a multi-layer cotton gauze system paired with a specialized tacking agent, creating an intricate mesh that traps contaminants while maintaining robust airflow for everyday driving.

  • Engineered power: state-of-the-art media is designed to increase airflow and support throttle response
  • 4 layers of protection: premium cotton gauze with a tacking agent captures contaminants before they reach the intake
  • Rugged construction: durable materials and modern build for long-lasting performance
  • Clean every 75,000 miles: under normal highway use, maintenance intervals extend toward years of use
  • Easy installation: pre-oiled and drop-in ready into your factory air box for a quick upgrade
  • Universal fitment: compatible with a variety of applications and vehicle types
  • Reduces waste: reusable design helps cut disposable filter waste and packaging
  • No-hassle warranty: 1-year limited warranty for added peace of mind
  • Made in USA: built in the USA for trusted quality and reliability

In real-world driving, you may notice a crisper engine response and steadier airflow during acceleration. While outcomes vary by vehicle and condition, the filter’s washable design supports repeated use and helps you avoid frequent replacements.
