Using this K&N air filter is easy. First, open your vehicle's factory air box. Carefully remove the old air filter and place the K&N replacement filter in its spot. Make sure it fits snugly. As for maintenance, it's recommended to clean the filter every 50,000 miles or as needed, depending on your driving conditions. To clean it, use a K&N filter cleaning kit. First, spray the cleaning solution on the filter and let it soak for a few minutes. Then, rinse it gently with water from the clean side to the dirty side. Let it dry completely before re - oiling it with K&N filter oil. When handling the filter, avoid using sharp objects that could damage the cotton media. If you're not sure about any step, consult your vehicle's manual or K&N's customer support.
