Why choose a Pipercross foam panel filter
Pipercross uses multi layered foam technology instead of cotton or paper media. Foam has a higher dirt holding capacity and maintains flow as the miles build up. In real world driving this means the Pipercross panel filter sustains strong airflow for longer, helping your BMW 120i maintain consistent performance where thin paper or cotton elements can start to restrict intake flow.
The triple layer foam design is the key. The outer coarse foam captures larger debris, the middle medium foam collects the bulk of particles, and the inner fine foam traps the remaining fine matter. This progressive filtration approach gives outstanding protection while keeping intake resistance low.
