How the triple-layer foam works

Three progressively finer foam layers capture debris without choking the intake path. The coarse outer layer stops larger particles, the mid layer traps the bulk of road dust and the fine inner layer deals with the remaining microscopic contaminants. This progressive filtration maintains strong airflow for longer and makes cleaning straightforward with a suitable foam filter cleaning solution.

Compatibility

Model: BMW 3 Series F30 and F31 320i, engine code N20B20A
