How often should I clean this filter?

K&N recommends cleaning your filter every 50,000 miles under normal highway driving conditions. If you drive in dusty or off-road conditions, you may need to clean it more frequently. Regular cleaning will help maintain proper airflow and engine performance.

What is the flange size on this filter?

This filter has a 2.75 inch (2-3/4in) flange. Make sure this matches your intake pipe's outer diameter. Using the correct size ensures a secure and airtight connection.

What cleaning products should I use?

K&N recommends using their synthetic air filter cleaner to properly clean and re-oil this filter. Other cleaners may damage the synthetic media, reducing its effectiveness and lifespan. Using the correct cleaner ensures the filter performs as intended.
