How often should I clean my K&N air filter?

The cleaning interval depends on your driving conditions. K&N recommends cleaning the filter when it becomes visually dirty. In normal conditions, this is usually every 50,000 miles. If you drive in dusty or off-road conditions, you may need to clean it more often.

Do I need to oil the filter after cleaning?

Yes, the filter needs to be oiled after cleaning. K&N air filter oil is specially formulated to work with the cotton media. It helps trap dirt and allows for maximum airflow. Use only K&N air filter oil to avoid damaging the filter.

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

This K&N air filter is backed by K&N's 10-Year/Million Mile Limited Warranty. This means K&N will replace the filter if it's defective in materials or workmanship. The warranty does not cover damage caused by misuse, abuse, or improper cleaning.
