Why Pipercross foam outperforms paper and cotton
Pipercross use multi-layer foam technology instead of cotton or paper. Foam has a larger filtration capacity, so it maintains stronger airflow for longer. Where thin paper or cotton stretched over a V-shaped wire frame can begin to restrict, the Pipercross triple-layer foam keeps flowing and helps your 420i sustain peak performance.
The triple-layer design delivers outstanding engine protection:
- Outer layer: coarse foam to capture larger particles
- Middle layer: medium foam to trap the majority of contaminants
- Inner layer: fine foam to catch the remaining fine particles
Fitment
- BMW 4 Series F32 420i
- Engine code: B48B20A
- Model years from 01/16 where equipped with B48B20A
- Direct drop-in for the OEM airbox
Installation and maintenance
This is a straightforward drop-in panel filter swap with simple, tool-light installation. Cleaning is quick and easy thanks to the foam construction and does not suffer the dirt trapping seen in V-shaped filter grooves.
