Using your K&N air filter is a breeze. First, locate your vehicle's factory air box. Open it up and remove the old air filter. Then, simply drop in the K&N replacement filter. Make sure it fits snugly and close the air box. As for maintenance, check your filter regularly, especially if you drive in dusty or dirty conditions. When it gets dirty, you can wash it. Use a K&N filter cleaning kit, which usually comes with a cleaner and oil. Follow the instructions on the kit to wash and re - oil the filter. This will keep it working at its best. Remember, this filter is built to last, but proper care will ensure it serves you well for the long run.
