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

The cleaning interval depends on your driving conditions. In normal conditions, K&N recommends cleaning and re-oiling every 50,000 miles. If you drive in dusty or off-road conditions, you may need to clean it more often.

What do I need to clean and re-oil my K&N air filter?

You'll need a K&N air filter cleaning kit, which includes both the air filter cleaner and air filter oil. Follow the instructions in the kit to properly clean and re-oil your filter.

Does this filter require any modifications to install?

No, this K&N air filter is designed to drop directly into your factory air box without any modifications. Simply remove the old filter and replace it with the K&N filter.
