Description
A premium charcoal cabin filter from MANN designed to restore clean, fresh air inside your Audi. The CUK 3037 uses activated carbon layers to effectively trap dust, pollen, harmful gases, and unpleasant odours — improving both air quality and driving comfort.
This filter is a direct replacement for Audi B6 and B7 A4, S4, and RS4 models, including popular engines like the 2.0T, 3.2i, and 4.2 FSI. Built to OEM quality standards, Mann Filters ensures a precise fit and long service life, delivering excellent filtration without restricting airflow.
We recommend replacing your cabin filter every 12 months or 15,000 km to maintain optimal HVAC system performance and a cleaner cabin environment — especially important for allergy-prone passengers or urban commuters.
If you’ve noticed reduced air flow, musty smells, or simply haven’t replaced yours in a while, this is a simple, affordable upgrade your Audi will thank you for.
