Unlock Better Airflow with the K&N High-Flow Universal Clamp-On Filter

Designed to fit a wide range of vehicles, the K&N High-Flow air filter is engineered to maximize airflow while maintaining filtration efficiency. The washable, reusable design means you can clean and reuse it instead of buying disposable filters, potentially saving money over the life of your vehicle.

Why this filter stands out

• Engineered power: state-of-the-art filter media is designed to increase airflow and support smoother acceleration when conditions allow.
• Four layers of protection: premium cotton gauze, treated with a specialized tacking agent, creates a filtration mesh that traps contaminants while preserving air flow.
• Rugged construction: durable materials and precise manufacturing keep the filter performing across years of use.
• Long-life maintenance: the filter is designed to be cleaned periodically (roughly every 75,000 miles under normal highway driving, about 5 years at 15,000 miles/year) with the goal of lasting through many seasons.
• Easy installation: pre-oiled and ready to drop into most factory air boxes, enabling a straightforward upgrade without specialized tools.
• Universal fitment: designed for broad applicability, making it a versatile choice for many applications.
• Waste reduction: reusable filters help minimize disposable filter and packaging waste compared with traditional disposables.
• No-hassle warranty: backed by a 1-year limited warranty for peace of mind.
• Made in USA: trusted quality and reliability from U.S. manufacturing.
