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

K&N recommends cleaning and re-oiling your filter every 50,000 miles for normal highway use. If you drive in dusty conditions, you may need to clean it more often. Use a K&N filter cleaning kit to maintain the filter's performance.

Do I need to make any modifications to my vehicle to install this filter?

No, the K&N 33-5115 is designed to drop directly into your factory airbox. No modifications are necessary for installation. Just remove the old filter and drop this one in.

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

This filter is backed by K&N's No-Hassle Lifetime Limited Warranty. This means K&N will replace the filter if it's defective in materials or workmanship. The warranty does not cover damage from misuse or improper cleaning.
