Pipercross performance panel element for BMW F32 435i N55 2013 onwards

Give your turbocharged 3.0 BMW fresh lungs with this British-made Pipercross panel insert.

A quick, no-fuss upgrade that enhances everyday driving and spirited runs alike.

Why this foam filter is the smarter choice

Pipercross uses a triple-layer, multi-density foam construction that traps fine particles without choking flow. Compared with thin paper or cotton gauze, the foam media offers a far larger dirt holding capacity, so performance stays consistent for longer between services and airflow remains strong when you need it.

Hand built in Northamptonshire, England, each unit is crafted for durability and repeatable results. It is a quality, cleanable solution designed to outlast disposable filters and reduce waste.
