3-stage foam technology

The multi-layer construction uses graded foams to separate debris progressively. A coarse outer layer stops larger particles, a mid-density layer handles the bulk of road contaminants and a fine inner layer tidies up the smallest particulates. This design keeps airflow high for longer than disposable paper media while offering dependable engine protection.

Real-world results

We have fitted and supplied these to many BMW X1 18i owners and feedback is consistently positive. Customers report smoother acceleration, a subtle performance tone and far longer intervals between maintenance compared with standard filters.

Fitment

BMW X1 18i E84 - 03/2010 onwards. Replaces the original filter element inside the OEM air box. No tuning changes required.

Care and cleaning

Service intervals depend on driving conditions, but the foam design typically requires less frequent maintenance than many cotton alternatives. When required, simply clean and re-oil to restore peak performance.
