Ramair PRORAM Replacement Pleated Air Filter for BMW – PPF-9933
If you want a straightforward upgrade over your BMW’s standard paper air filter, this PRORAM pleated panel filter from Ramair is a solid, no-fuss choice. It sits directly in your existing airbox – no modifications needed – and is designed to flow more air than the factory filter while keeping the engine properly protected.
Ramair have been involved in motorsport filtration for over 35 years, and the PRORAM range brings that experience into a practical, road and track-friendly product. The filter uses a high-quality synthetic nanofiber media – a fine, tightly woven material that traps dirt particles effectively while allowing more air to pass through than a standard paper element. The pleated design increases the usable surface area of the filter, which is what helps improve airflow without compromising filtration.
Unlike a paper filter that needs replacing at regular intervals, this filter is washable and reusable for the life of the vehicle, making it a practical long-term investment.
