The Ramair Performance Panel Filter for Audi A4 B8 models is a direct replacement for the standard paper air filter, fitting inside the original OEM airbox. It uses Ramair's twin-layer Aeriform foam construction to provide improved airflow while maintaining effective filtration, making it a straightforward upgrade for road and performance applications.
The filter features twin-layer, fully reticulated foam that is MAF safe and designed to provide a balance of airflow and dust filtration. The foam is supported by a stainless steel cage structure, providing strength and stability within the factory airbox.
A rubber polymer surround gives the filter a durable, clean finish while helping to ensure a consistent sealing surface. The filter is also fully reusable and can be cleaned using the CK-003 filter maintenance kit, making it a practical alternative to repeatedly replacing the standard paper element.
