How does this filter affect engine performance?

By increasing airflow to the intake, the High-Flow media can help the engine breathe more freely during acceleration and under load. That can translate to more consistent throttle response and potential improvements in horsepower and acceleration depending on the vehicle and driving conditions.

• State-of-the-art cotton gauze media increases airflow up to 50% compared with some stock filters.
• Four layers of treated gauze trap contaminants while allowing higher air volume.
• Pre-oiled and ready to install for immediate performance benefits.

How often will I need to clean or maintain it?

K&N filters are washable and made for long-term use; under normal highway driving the filter typically only needs cleaning about every 75,000 miles. Cleaning frequency varies with environment — dusty or off-road conditions will require more frequent maintenance.

• Typical cleaning interval: approximately every 75,000 miles under normal conditions.
• Cleaner kit and re-oiling restore filtration and performance.
• Designed to outlast numerous disposable filters, reducing waste and replacement cost.

What are the construction and environmental benefits?

• Four layers of premium cotton gauze provide filtration and airflow balance.
