Using your K&N air filter is easy. First, locate your factory air box. Open it up and carefully remove the old air filter. Then, take your new K&N filter and place it into the air box. Make sure it fits snugly. Close the air box and you're good to go. As for maintenance, every 50,000 to 100,000 miles (depending on your driving conditions), it's time to clean the filter. Use a K&N filter cleaning kit. Wash the filter gently with the provided cleaner, then let it dry completely. Re - oil it with the K&N filter oil according to the instructions. Remember, always handle the filter carefully to avoid any damage. Also, don't use any other cleaners or oils that aren't recommended by K&N as it may void the warranty.
