Why choose multi density foam

Pipercross uses a tri foam construction that separates and captures contaminants across three distinct layers. The coarse outer layer deals with larger particles, the middle section handles the bulk of dust, and the fine inner layer protects against the smallest particulates. This design keeps airflow high even as the filter loads, so your diesel 4 Series can hold peak performance between services.
