Why choose Pipercross foam over cotton or paper?
Pipercross uses a special triple layer foam media rather than cotton or paper. Foam has a greater capacity for filtration, so it maintains higher airflow as it loads with dust. While thin cotton or paper stretched over V shaped wire frames can start to restrict airflow, Pipercross multi layer foam continues to perform, helping your BMW hold peak power for longer between services.
The outer coarse foam traps larger particles, the middle medium layer captures the majority of contaminants and the inner fine foam deals with the remaining micro particles. The result is excellent engine protection in all conditions with low maintenance.
