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. Depending on your driving conditions, you may need to service it more often. Inspect the filter regularly for excessive dirt buildup.

Do I need to oil this filter?

Yes, this is an oiled air filter. The oil is what traps the dirt and allows the filter to be more effective than a dry filter. You'll need to buy a K&N filter cleaning and oiling kit to properly maintain this filter.

Will this filter void my car's warranty?

In most cases, no. The Magnuson-Moss Warranty Act protects consumers from warranties being voided due to aftermarket parts, unless the part directly causes a failure. However, it's always a good idea to check with your dealer if you have concerns.
