Using your K&N air filter is easy. First, locate your vehicle's factory air box. Open it up, take out the old air filter, and then simply drop in your new K&N filter. Make sure it fits snugly in place and then close the air box. When it comes to maintenance, check your filter regularly. If it looks dirty or clogged, it's time to clean it. To clean the filter, use K&N's recommended cleaning kit. Wash the filter gently with the cleaning solution and then let it dry completely before re - oiling it with the provided oil. Apply the oil evenly to ensure proper filtration. Don't use any harsh chemicals or excessive force when cleaning, as this could damage the filter. Also, always refer to your vehicle's manual and K&N's warranty information for any specific instructions or limitations.
