How often should I clean and re-oil my K&N air filter?

K&N recommends cleaning and re-oiling your filter every 50,000 miles under normal driving conditions. If you drive in dusty or off-road conditions, you may need to clean it more frequently. Use a K&N filter cleaning kit to properly clean and re-oil the filter.

Does this filter require any modifications to install?

No, this K&N air filter is designed as a direct drop-in replacement for your factory air filter. It installs directly into your factory air box without any modifications. Just remove the old filter and replace it with the K&N filter.

What is the warranty on this K&N air filter?
