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

The cleaning interval depends on your driving conditions. K&N recommends inspecting your filter every 25,000 to 50,000 miles and cleaning it when you see a buildup of dirt and debris. Use a K&N filter cleaning kit to maintain the filter's performance and warranty.

Does this filter come pre-oiled?

Yes, K&N air filters come pre-oiled from the factory, ready for installation. The oil is what traps the dirt and debris, so it's important to re-oil the filter after cleaning. Use only K&N filter oil to avoid damaging the filter material.

Will this filter void my vehicle's warranty?

In the US, using an aftermarket air filter like this K&N will not void your vehicle's warranty, thanks to the Magnuson-Moss Warranty Act. As long as the filter is properly maintained and doesn't cause any damage, your warranty remains in effect.
