The K&N X-Stream 9-inch top replaces the lid on an existing round air filter to increase airflow. X-Stream tops channel additional air into the intake while remaining washable and reusable like other K&N filters. This 9-inch flow top is a simple upgrade for round performance filters, offering improved engine breathing without replacing the entire filter element.
