Why foam makes sense

Pipercross uses multi-layer reticulated foam with progressive porosity to trap contaminants through the depth of the media rather than just on the surface. That higher dust capacity keeps flow steadier for longer, helping your engine breathe freely between cleans. No fiddly wire grooves that clog. Just reliable filtration and consistent airflow.

Fitment

Designed for BMW X4 F26 petrol 35i variants including xDrive 35i and 35 iX from 2014 onwards. Direct swap for the standard air filter in the OEM airbox. If you are unsure on compatibility, get in touch and we will be happy to help.
