The aFe Power MagnumFLOW Pro DRY S air filter is an oil-free, direct replacement for your BMW's restrictive factory paper filter. Engineered for maximum convenience and performance, this filter features three layers of progressive synthetic media that provide high filtration efficiency and excellent dust-holding capacity without the need for filter oil. The tall, evenly spaced pleats extend the service cycle between cleanings, making it a low-maintenance solution for enthusiasts.

Built for long-term durability, the filter is constructed with a 100-percent polyurethane frame on all sides to resist degradation from engine bay heat and chemicals. An integrated urethane bump seal ensures a tight, leak-free fit within the factory airbox. This washable and reusable filter provides a sustainable alternative to disposable elements while improving airflow for horsepower and torque gains.
