Why choose performance foam over cotton or paper

Pipercross uses a three-layer reticulated foam matrix that flows strongly even as it loads with particulates. Compared with thin paper or cotton gauze, the deep foam structure offers greater dirt capacity and sustained airflow, helping your 3 Series breathe consistently between services.

Triple-layer design for clean, consistent intake flow

The filter media is engineered for progressive filtration:

• Outer layer captures larger debris
• Mid layer controls the bulk of airborne contaminants
• Inner layer targets fine particles for dependable protection

This construction supports high flow and effective filtration, ideal for daily driving and spirited use on UK roads.
