Why Pipercross foam beats paper and cotton
Pipercross uses multi-layer reticulated foam rather than paper or cotton because foam has a higher dirt capacity while maintaining superior airflow. In real-world terms, a Pipercross panel filter will flow stronger for longer, helping your 640d sustain peak performance compared with thin paper or cotton media stretched over a wire frame. Where paper and cotton begin to restrict, the triple-layer foam keeps air moving.
Triple-layer filtration for strong performance and engine protection
Each Pipercross panel filter uses a three-stage foam element: a coarse outer layer to catch larger particles, a medium middle layer to capture most debris, and a fine inner layer to trap the remainder. This progressive design delivers excellent engine protection in all conditions while reducing maintenance and extending cleaning intervals.
