How often should I clean the K&N 77-2615KC air filter?

[VanJulia]

To keep your K&N 77-2615KC Performance Air Intake System performing at its best, K&N recommends cleaning the air filter every 100,000 miles. However, this is a general guideline. If you frequently drive in dusty or off-road conditions, you may need to clean it more often. It's a good idea to visually inspect the filter every 25,000 miles. If you can no longer see the filter screen in some areas, it's time for a cleaning. You can maintain your K&N air filter with the K&N filter Recharger service kit, using either part number 99-5050 or 99-5000. Be sure to follow the instructions included with the kit. Proper maintenance ensures your K&N intake system continues to provide optimal performance and lasts for a long time.
