Using the K&N air filter is a breeze. Just remove your old air filter from the factory air box and drop this new one in. Make sure it's properly seated to get the best performance. As for maintenance, it's recommended to clean the filter every 50,000 - 100,000 miles depending on your driving conditions. To clean, use a K&N filter cleaning kit. First, spray the cleaner on the filter and let it soak for a few minutes. Then, gently rinse it with water. Let it dry completely before applying the filter oil. When applying the oil, follow the instructions on the oil bottle for the right amount. Keep in mind, don't use harsh chemicals or tools on the filter as it can damage the cotton media. Always store the filter in a dry place when not in use.
