Using your K&N air filter is easy. First, locate your vehicle's factory air box. Open it up and remove the old air filter. Then, simply drop the K&N filter into the air box and close it back up. That's it! As for maintenance, every 50,000 - 100,000 miles (depending on your driving conditions), you'll want to clean the filter. You can use a K&N air filter cleaning kit. Just follow the instructions on the kit to wash the filter and re - oil it. When handling the filter, be gentle to avoid damaging the cotton media. Also, make sure the filter is completely dry before re - installing it. If you have any questions or concerns, don't hesitate to reach out to K&N's customer service.
