The K&N E-2021 high-flow air filter is a reusable filter for the BMW 5 Series. It is made from multilayer, oil-impregnated cotton material with four layers that capture dust, dirt and contaminants while allowing airflow. It is a direct replacement for the factory filter and comes pre-oiled, ready to install.
Under normal highway driving conditions, it needs to be cleaned every 75,000 km or every 5 years.
