How often should I clean the filter?

The cleaning intervals depend on your driving conditions. Inspect the filter regularly, and clean it when you see a buildup of dirt and debris. A dirty filter restricts airflow and reduces performance.

What do I use to clean this filter?

K&N sells a recharge kit with cleaner and oil, designed to maintain the filter's performance and extend its lifespan. Using other oils can damage the filter material and reduce its effectiveness.

Does this filter come pre-oiled?

Yes, this K&N filter comes pre-oiled and ready to install. You don't need to oil it before the initial use. Just install it and you're good to go.
