Using your K&N air filter is easy. Just remove your old filter from the factory air box and drop this new one in. It's a simple swap that you can do on your own. When it comes to maintenance, it's recommended to check the filter every 10,000 to 15,000 miles. If it looks dirty, you can wash it. To wash, use a K&N filter cleaner and gently rinse it with water. Let it dry completely before oiling it with K&N filter oil. Make sure to follow the oiling instructions on the oil bottle. Avoid using harsh chemicals or high - pressure water as it can damage the filter. Always keep your filter clean to ensure it continues to perform at its best and provides maximum airflow and horsepower for your Ferrari.
