Why foam filtration is a smart upgrade

Unlike thin paper or cotton, Pipercross uses a progressive, multi layer foam that holds more contaminants without choking the intake. The outer coarse layer stops larger debris, the mid layer captures the bulk of particles, and the inner fine layer takes care of the remaining fine matter. The result is sustained airflow as the miles add up, helping your BMW 120i maintain consistent performance with strong protection.

Real world feedback

We run this filter on our own cars and have installed it for customers. The verdict is consistently positive, highlighting quality construction, straightforward fitting, durable foam media and the value of a lifetime warranty.

Care and maintenance

Thanks to the high dirt holding capacity of the foam, cleaning is required less often than with cotton alternatives. When servicing, remove, clean and refit to keep airflow strong for the long term.
