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.
