Frequently Asked Questions

How do I locate my cabin air filter?

Cabin air filters have only recently been integrated into U.S. automobile AC/heating systems, so you’ll need to check your owner’s manual to determine if your vehicle has one. If it does, it’s typically found in one of three places:

Under the hood, near the windshield
Underneath the dashboard
Behind the glove compartment

How and how often do I need to clean my K&N® replacement cabin air filter?

Air filter cleaning instructions and service intervals are available at the How to Clean K&N Air Filter Products page.

What is the cabin air filter for?

Cabin air filters are used to filter the air that is coming through your car’s HVAC system and into the interior of your car.

Is there a difference between a cabin air filter and a regular air filter?

Most modern vehicles are sold including an air filter in the engine bay used to protect the engine from contaminants, in addition to a cabin air filter used to filter the air entering your vehicles interior.

Can a K&N® air filter be made at the factory for any application?

With over 6,000 individual part numbers available, there is a very good chance K&N has an existing product to meet your filter needs. In the event we do not have an air filter available, you may look into the K&N Custom Filter Program, where we modify existing parts to meet customers' exact needs.
