1. Product Overview
The K&N High-Flow Engine Air Filter is engineered to enhance engine performance by increasing airflow. Unlike disposable paper filters, K&N Air Filters are washable, reusable, and designed for long-term use. They are backed by a 10-Year/Million Mile Limited Warranty and contribute to reducing landfill waste.

Key Features:
- Engineered Power: State-of-the-art air filter media is designed to increase horsepower and acceleration as well as improve overall engine performance.
- Rugged Construction: Manufactured with durable, premium materials and state-of-the-art construction methods to last a lifetime.
- 4 Layers of Protection: Multiple layers of premium cotton gauze treated with a specially-designed tacking agent work together to create an intricate mesh of engine filter media that is designed to block and trap harmful contaminants.
- Eco-Friendly: Using a washable, reusable engine air filter helps reduce replacement air filter waste—a K&N air filter is designed to last longer than 10 or more disposable filters.

2. Installation Guide
The K&N High-Flow Engine Air Filter is designed for straightforward installation, typically completed in minutes as a direct drop-in replacement for your factory air box.
General Installation Steps:
- Locate your vehicle's air box.
- Open the air box cover. This typically involves unclipping latches or unscrewing fasteners.
- Remove the old air filter.
- Insert the new K&N High-Flow Engine Air Filter into the air box, ensuring it is properly seated.
- Close and securely latch the air box cover.

3. Operating Considerations
Once installed, the K&N High-Flow Engine Air Filter operates continuously to provide improved airflow to your engine. No special operating procedures are required beyond regular vehicle use.
The filter's design aims to enhance engine performance and acceleration by allowing up to 50% more airflow compared to traditional disposable filters.
4. Maintenance and Cleaning
The K&N High-Flow Engine Air Filter is designed to be washable and reusable, offering significant longevity and reducing waste.
Cleaning Schedule:
- Under normal highway driving conditions, the engine air filter only needs cleaning approximately every 75,000 miles.
- This translates to about once every 5 years, based on an average of 15,000 miles driven annually.
Cleaning Process:
To clean the filter, use a K&N Recharger Kit (sold separately) which includes a cleaning solution and filter oil. Follow the instructions provided with the cleaning kit for optimal results.




5. Troubleshooting
If you experience any issues after installing your K&N High-Flow Engine Air Filter, please ensure the filter is correctly seated within the air box and the cover is securely latched. An improperly sealed air box can lead to unfiltered air entering the engine.
For persistent issues or concerns, consult a qualified automotive technician or contact K&N customer support.
